Is Open Two-Factor Authenticator safe?
Open Two-Factor Authenticator stores TOTP secrets in sync storage using password-hash AES encryption.
When you add an authenticator entry, the extension encrypts the TOTP shared secret with an AES key derived directly from the master password's SHA-256 hash. The confirmed claim says the encrypted secret is saved in chrome.storage.sync, with a 4-character minimum password and no salt, PBKDF, or authentication tag.
