# Sign-in protection

Sign-in is rate-limited per account and per address, backed by the database so it survives a restart and works across instances. A suspended account is refused, repeated failures raise an alert.

## Why it matters

The limiter fails open if the database blips, because one that locks everyone out on a hiccup is worse than one that briefly stops counting.
