Once we lost the user account DB at a startup to database data loss and some other day, someone logged into mongodb and dropped all the tables and backups were not test before, so they did not work.

After that we no longer store these details.

We've been using amazon cognito with lambda authorizers.

That sounds like the problem is how you keep your database permissions and backups, not anything to do with auth.
