Passwords are stored as one-way hashes
Passwords are hashed with Argon2id — the algorithm designed to be slow and memory-hard specifically to frustrate cracking — and only the hash is ever stored. There is no path back to the original, which is why we can help someone reset a password but can never tell them what it was.
- Changing a password requires the current one, and reusing it is refused
- A successful reset immediately revokes every existing session for that account
