♻️ Current situation

Current password check code allows for the hash to be guessed utilizing a timing attack.

💡 Proposed solution

Simple update to the password check function that utilizes crypto.timingSafeEqual such that comparisons are always the same time.

⚙️ Release Notes

Increased password security with timing safe comparison

Testing

Testing should be covered by existing cases in auth.e2e-spec.ts

Hi @BlenderDude
Thanks for your time on this PR.

Can you explain the changes in laymans terms?

I guess this would not result in any difference in behaviour for a standard user logging in?
