Features
- Encryption — the vault is one file (
~/.local/share/synpass/vault.json): the key is derived from the master password with Argon2id, entries are encrypted with XChaCha20-Poly1305. - Entries — title, username, password, website and notes; favorites, recently copied, search; copy the password or username in one click, open the website.
- Generator — length, uppercase letters, digits, symbols, no look-alike characters (0/O, 1/l/I); a strength meter.
- Large view — the password character by character with numbering and character classes, easy to type on another device.
- Sync — entries are merged with devices linked through synlink (phone, other computer) in both directions; deletions reach the other devices too. A copied password goes to the shared clipboard of linked devices.
- Safety — auto-lock after a period of inactivity, clipboard cleared after a set time (here and on linked devices), change of master password, an optional security question to recover access.
- Computer and phone — two columns on a wide window, list → entry on a phone; 14 languages.
