Replace old rate limiting in password login flow with "SystemAction" rate limiting

Authored by epriestley on Jul 19 2019, 5:21 PM.



Depends on D20667. Ref T13343. Password auth currently uses an older rate limiting mechanism, upgrade it to the modern "SystemAction" mechanism.

This mostly just improves consistency, although there are some tangential/theoretical benefits:

  • it's not obvious that making the user log GC very quickly could disable rate limiting;
  • if we let you configure action limits in the future, which we might, this would become configurable for free.
Test Plan
  • With CAPTCHAs off, made a bunch of invalid login attempts. Got rate limited.
  • With CAPTCHAs on, made a bunch of invalid login attempts. Got downgraded to CAPTCHAs after a few.

These limits have changed slightly: captcha from "5 per 15 minutes" to "10 per hour", and logins from "32 per 15 minutes" to "100 per hour".
