# DATABASE_URL=postgresql://user:password@host[:port]/database_name

## Enable WAL for the DB
## Set to false to avoid enabling WAL during startup.
## Note that if the DB already has WAL enabled, you will also need to disable WAL in the DB,
## this setting only prevents Vaultwarden from automatically enabling it on start.
## Please read project wiki page about this setting first before changing the value as it can
## cause performance degradation or might render the service unable to start.

### Schedule jobs ###
#####################

## Job scheduler settings
##
## Job schedules use a cron-like syntax (as parsed by https://crates.io/crates/cron),
## and are always in terms of UTC time (regardless of your local time zone settings).
##
## The schedule format is a bit different from crontab as crontab does not contains seconds.
## You can test the the format here: https://crontab.guru, but remove the first digit!
## SEC  MIN   HOUR   DAY OF MONTH    MONTH   DAY OF WEEK
## "0   30   9,12,15     1,15       May-Aug  Mon,Wed,Fri"
## "0   30     *          *            *          *     "
## "0   30     1          *            *          *     "
##
## How often (in ms) the job scheduler thread checks for jobs that need running.
## Set to 0 to globally disable scheduled jobs.
# JOB_POLL_INTERVAL_MS=30000
##
## Cron schedule of the job that checks for Sends past their deletion date.
## Defaults to hourly (5 minutes after the hour). Set blank to disable this job.
# SEND_PURGE_SCHEDULE="0 5 * * * *"
##
## Cron schedule of the job that checks for trashed items to delete permanently.
## Defaults to daily (5 minutes after midnight). Set blank to disable this job.
# TRASH_PURGE_SCHEDULE="0 5 0 * * *"
##
## Cron schedule of the job that checks for incomplete 2FA logins.
## Defaults to once every minute. Set blank to disable this job.
# INCOMPLETE_2FA_SCHEDULE="30 * * * * *"
##
## Cron schedule of the job that sends expiration reminders to emergency access grantors.
## Defaults to hourly (3 minutes after the hour). Set blank to disable this job.
# EMERGENCY_NOTIFICATION_REMINDER_SCHEDULE="0 3 * * * *"
##
## Cron schedule of the job that grants emergency access requests that have met the required wait time.
## Defaults to hourly (7 minutes after the hour). Set blank to disable this job.
# EMERGENCY_REQUEST_TIMEOUT_SCHEDULE="0 7 * * * *"
##
## Cron schedule of the job that cleans old events from the event table.
## Defaults to daily. Set blank to disable this job. Also without EVENTS_DAYS_RETAIN set, this job will not start.
# EVENT_CLEANUP_SCHEDULE="0 10 0 * * *"
## Number of days to retain events stored in the database.
## If unset (the default), events are kept indefinitely and the scheduled job is disabled!
# EVENTS_DAYS_RETAIN=
##
## Cron schedule of the job that cleans old auth requests from the auth request.
## Defaults to every minute. Set blank to disable this job.
# AUTH_REQUEST_PURGE_SCHEDULE="30 * * * * *"
##
## Cron schedule of the job that cleans expired Duo contexts from the database. Does nothing if Duo MFA is disabled or set to use the legacy iframe prompt.
## Defaults to every minute. Set blank to disable this job.
# DUO_CONTEXT_PURGE_SCHEDULE="30 * * * * *"

## Domain settings
## The domain must match the address from where you access the server
## It's recommended to configure this value, otherwise certain functionality might not work,
## like attachment downloads, email links and U2F.
## For U2F to work, the server must use HTTPS, you can use Let's Encrypt for free certs
## To use HTTPS, the recommended way is to put Vaultwarden behind a reverse proxy
## Details:
## - https://github.com/dani-garcia/vaultwarden/wiki/Enabling-HTTPS

# TRASH_AUTO_DELETE_DAYS=

## Number of minutes to wait before a 2FA-enabled login is considered incomplete,
## resulting in an email notification. An incomplete 2FA login is one where the correct
## master password was provided but the required 2FA step was not completed, which
## potentially indicates a master password compromise. Set to 0 to disable this check.
## This setting applies globally to all users.
# INCOMPLETE_2FA_TIME_LIMIT=3

## Disable icon downloading
## Set to true to disable icon downloading in the internal icon service.
## This still serves existing icons from $ICON_CACHE_FOLDER, without generating any external
## network requests. $ICON_CACHE_TTL must also be set to 0; otherwise, the existing icons
## will be deleted eventually, but won't be downloaded again.
# DISABLE_ICON_DOWNLOAD=false

## Controls if new users can register
# SIGNUPS_ALLOWED=true

## Note that setting this option to true prevents logins until the email address has been verified!
## The welcome email will include a verification link, and login attempts will periodically
## trigger another verification email to be sent.
# SIGNUPS_VERIFY=false

## If SIGNUPS_VERIFY is set to true, this limits how many seconds after the last time
## an email verification link has been sent another verification email will be sent
# SIGNUPS_VERIFY_RESEND_TIME=3600

## unauthenticated access to potentially sensitive data.
# SHOW_PASSWORD_HINT=false

#########################
### Advanced settings ###
#########################

## Client IP Header, used to identify the IP of the client, defaults to "X-Real-IP"
## Set to the string "none" (without quotes), to disable any headers and just use the remote IP
# IP_HEADER=X-Real-IP

## Icon service
## The predefined icon services are: internal, bitwarden, duckduckgo, google.
## To specify a custom icon service, set a URL template with exactly one instance of `{}`,
## which is replaced with the domain. For example: `https://icon.example.com/domain/{}`.
##
## `internal` refers to Vaultwarden's built-in icon fetching implementation.
## If an external service is set, an icon request to Vaultwarden will return an HTTP
## redirect to the corresponding icon at the external service. An external service may
## be useful if your Vaultwarden instance has no external network connectivity, or if
## you are concerned that someone may probe your instance to try to detect whether icons
## for certain sites have been cached.
# ICON_SERVICE=internal

## Icon redirect code
## The HTTP status code to use for redirects to an external icon service.
## The supported codes are 301 (legacy permanent), 302 (legacy temporary), 307 (temporary), and 308 (permanent).
## Temporary redirects are useful while testing different icon services, but once a service
## has been decided on, consider using permanent redirects for cacheability. The legacy codes
## are currently better supported by the Bitwarden clients.
# ICON_REDIRECT_CODE=302

## Cache time-to-live for successfully obtained icons, in seconds (0 is "forever")
## Default: 2592000 (30 days)
# ICON_CACHE_TTL=2592000
## Cache time-to-live for icons which weren't available, in seconds (0 is "forever")
## Default: 2592000 (3 days)
# ICON_CACHE_NEGTTL=259200

## Icon download timeout
## Configure the timeout value when downloading the favicons.
## The default is 10 seconds, but this could be to low on slower network connections
# ICON_DOWNLOAD_TIMEOUT=10

## Block HTTP domains/IPs by Regex
## Any domains or IPs that match this regex won't be fetched by the internal HTTP client.
## Useful to hide other servers in the local network. Check the WIKI for more details
## NOTE: Always enclose this regex withing single quotes!
# HTTP_REQUEST_BLOCK_REGEX='^(192\.168\.0\.[0-9]+|192\.168\.1\.[0-9]+)$'

## Enabling this will cause the internal HTTP client to refuse to connect to any non global IP address.
## Useful to secure your internal environment: See https://en.wikipedia.org/wiki/Reserved_IP_addresses for a list of IPs which it will block
# HTTP_REQUEST_BLOCK_NON_GLOBAL_IPS=true

## Client Settings
## Enable experimental feature flags for clients.
## This is a comma-separated list of flags, e.g. "flag1,flag2,flag3".
##
## The following flags are available:
## - "autofill-overlay": Add an overlay menu to form fields for quick access to credentials.
## - "autofill-v2": Use the new autofill implementation.
## - "browser-fileless-import": Directly import credentials from other providers without a file.
## - "extension-refresh": Temporarily enable the new extension design until general availability (should be used with the beta Chrome extension)
## - "fido2-vault-credentials": Enable the use of FIDO2 security keys as second factor.
## - "inline-menu-positioning-improvements": Enable the use of inline menu password generator and identity suggestions in the browser extension.
## - "ssh-key-vault-item": Enable the creation and use of SSH key vault items. (Needs clients >=2024.12.0)
## - "ssh-agent": Enable SSH agent support on Desktop. (Needs desktop >=2024.12.0)
# EXPERIMENTAL_CLIENT_FEATURE_FLAGS=fido2-vault-credentials

## Require new device emails. When a user logs in an email is required to be sent.
## If sending the email fails the login attempt will fail!!
# REQUIRE_DEVICE_EMAIL=false

## Enable extended logging, which shows timestamps and targets in the logs
# EXTENDED_LOGGING=true

## Timestamp format used in extended logging.
## Format specifiers: https://docs.rs/chrono/latest/chrono/format/strftime
# LOG_TIMESTAMP_FORMAT="%Y-%m-%d %H:%M:%S.%3f"

## Logging to Syslog
## This requires extended logging
# USE_SYSLOG=false

## Logging to file
# LOG_FILE=/path/to/log

## Log level
## Change the verbosity of the log output
## Valid values are "trace", "debug", "info", "warn", "error" and "off"
## Setting it to "trace" or "debug" would also show logs for mounted routes and static file, websocket and alive requests
## For a specific module append a comma separated `path::to::module=log_level`
## For example, to only see debug logs for icons use: LOG_LEVEL="info,vaultwarden::api::icons=debug"
# LOG_LEVEL=info

## Token for the admin interface, preferably an Argon2 PCH string
## Vaultwarden has a built-in generator by calling `vaultwarden hash`
## For details see: https://github.com/dani-garcia/vaultwarden/wiki/Enabling-admin-page#secure-the-admin_token
## If not set, the admin panel is disabled
## New Argon2 PHC string
## Note that for some environments, like docker-compose you need to escape all the dollar signs `$` with an extra dollar sign like `$$`
## Also, use single quotes (') instead of double quotes (") to enclose the string when needed
# ADMIN_TOKEN='$argon2id$v=19$m=65540,t=3,p=4$MmeKRnGK5RW5mJS7h3TOL89GrpLPXJPAtTK8FTqj9HM$DqsstvoSAETl9YhnsXbf43WeaUwJC6JhViIvuPoig78'
## Old plain text string (Will generate warnings in favor of Argon2)
# ADMIN_TOKEN=Vy2VyYTTsKPv8W5aEOWUbB/Bt3DEKePbHmI4m9VcemUMS2rEviDowNAFqYi1xjmp

## Enable this to bypass the admin panel security. This option is only
## meant to be used with the use of a separate auth layer in front
# DISABLE_ADMIN_TOKEN=false

## Number of seconds, on average, between admin login requests from the same IP address before rate limiting kicks in.
# ADMIN_RATELIMIT_SECONDS=300
## Allow a burst of requests of up to this size, while maintaining the average indicated by `ADMIN_RATELIMIT_SECONDS`.
# ADMIN_RATELIMIT_MAX_BURST=3

## Set the lifetime of admin sessions to this value (in minutes).
# ADMIN_SESSION_LIFETIME=20

## Allowed iframe ancestors (Know the risks!)
## https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/frame-ancestors
## Allows other domains to embed the web vault into an iframe, useful for embedding into secure intranets
## This adds the configured value to the 'Content-Security-Policy' headers 'frame-ancestors' value.
## Multiple values must be separated with a whitespace.
# ALLOWED_IFRAME_ANCESTORS=

## Allowed connect-src (Know the risks!)
## https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/connect-src
## Allows other domains to URLs which can be loaded using script interfaces like the Forwarded email alias feature
## This adds the configured value to the 'Content-Security-Policy' headers 'connect-src' value.
## Multiple values must be separated with a whitespace. And only HTTPS values are allowed.
## Example: "https://my-addy-io.domain.tld https://my-simplelogin.domain.tld"
# ALLOWED_CONNECT_SRC=""

## Number of seconds, on average, between login requests from the same IP address before rate limiting kicks in.
# LOGIN_RATELIMIT_SECONDS=60
## Allow a burst of requests of up to this size, while maintaining the average indicated by `LOGIN_RATELIMIT_SECONDS`.
## Note that this applies to both the login and the 2FA, so it's recommended to allow a burst size of at least 2.
# LOGIN_RATELIMIT_MAX_BURST=10

## BETA FEATURE: Groups
## Controls whether group support is enabled for organizations
## This setting applies to organizations.
## Disabled by default because this is a beta feature, it contains known issues!
## KNOW WHAT YOU ARE DOING!
# ORG_GROUPS_ENABLED=false

## Increase secure note size limit (Know the risks!)
## Sets the secure note size limit to 100_000 instead of the default 10_000.
## WARNING: This could cause issues with clients. Also exports will not work on Bitwarden servers!
## KNOW WHAT YOU ARE DOING!
# INCREASE_NOTE_SIZE_LIMIT=false

## Enforce Single Org with Reset Password Policy
## Enforce that the Single Org policy is enabled before setting the Reset Password policy
## Bitwarden enforces this by default. In Vaultwarden we encouraged to use multiple organizations because groups were not available.
## Setting this to true will enforce the Single Org Policy to be enabled before you can enable the Reset Password policy.
# ENFORCE_SINGLE_ORG_WITH_RESET_PW_POLICY=false

########################
### MFA/2FA settings ###
########################

## Yubico (Yubikey) Settings
## Set your Client ID and Secret Key for Yubikey OTP
## You can generate it here: https://upgrade.yubico.com/getapikey/
## You can optionally specify a custom OTP server
# YUBICO_CLIENT_ID=11111
# YUBICO_SECRET_KEY=AAAAAAAAAAAAAAAAAAAAAAAA
# YUBICO_SERVER=http://yourdomain.com/wsapi/2.0/verify

## Duo Settings
## You need to configure the DUO_IKEY, DUO_SKEY, and DUO_HOST options to enable global Duo support.
## Otherwise users will need to configure it themselves.
## Create an account and protect an application as mentioned in this link (only the first step, not the rest):
## https://help.bitwarden.com/article/setup-two-step-login-duo/#create-a-duo-security-account
## Then set the following options, based on the values obtained from the last step:
# DUO_IKEY=<Client ID>
# DUO_SKEY=<Client Secret>
# DUO_HOST=<API Hostname>
## After that, you should be able to follow the rest of the guide linked above,
## ignoring the fields that ask for the values that you already configured beforehand.
##
## If you want to attempt to use Duo's 'Traditional Prompt' (deprecated, iframe based) set DUO_USE_IFRAME to 'true'.
## Duo no longer supports this, but it still works for some integrations.
## If you aren't sure, leave this alone.
# DUO_USE_IFRAME=false

## Email 2FA settings
## Email token size
## Number of digits in an email 2FA token (min: 6, max: 255).
## Note that the Bitwarden clients are hardcoded to mention 6 digit codes regardless of this setting!
# EMAIL_TOKEN_SIZE=6
##
## Token expiration time
## Maximum time in seconds a token is valid. The time the user has to open email client and copy token.
# EMAIL_EXPIRATION_TIME=600
##
## Maximum attempts before an email token is reset and a new email will need to be sent.
# EMAIL_ATTEMPTS_LIMIT=3
##
## Setup email 2FA regardless of any organization policy
# EMAIL_2FA_ENFORCE_ON_VERIFIED_INVITE=false
## Automatically setup email 2FA as fallback provider when needed
# EMAIL_2FA_AUTO_FALLBACK=false

## Other MFA/2FA settings
## Disable 2FA remember
## Enabling this would force the users to use a second factor to login every time.
## Note that the checkbox would still be present, but ignored.
# DISABLE_2FA_REMEMBER=false
##
## Authenticator Settings
## Disable authenticator time drifted codes to be valid.
## TOTP codes of the previous and next 30 seconds will be invalid
##
## According to the RFC6238 (https://tools.ietf.org/html/rfc6238),
## we allow by default the TOTP code which was valid one step back and one in the future.
## This can however allow attackers to be a bit more lucky with there attempts because there are 3 valid codes.
## You can disable this, so that only the current TOTP Code is allowed.
## Keep in mind that when a sever drifts out of time, valid codes could be marked as invalid.
## In any case, if a code has been used it can not be used again, also codes which predates it will be invalid.
# AUTHENTICATOR_DISABLE_TIME_DRIFT=false
