Your devices.

Security with a human in the loop
A password should not be the only key.
Traditional vaults often treat the right master password as the whole decision. Authier also understands which devices belong to you, and its configurable approval policy can keep an unfamiliar browser pending until you approve it.
Encrypted before sync
Credentials and TOTP secrets are encrypted locally before the API stores them.
Passwords and TOTP
Keep logins and time-based one-time passwords together, then fill both in the browser.
Open source
Inspect the code, follow development, report issues, or contribute under AGPL-3.0.
