Pros and cons
PassKnight
- Named developer and public source code — unusually transparent for this category
- k-Anonymity design means the full password is never transmitted
- Actively maintained — code updated within the week before this review
- Free core functionality, Stars tip is optional
- Interface is Russian-only, no confirmed English toggle
- Very small project with limited track record and no press coverage found
- No formal privacy policy beyond the claims stated in the README
TOTP-Authenticator
- Genuinely different, useful category — 2FA, not just passwords
- No separate authenticator app to install
- Follows the same open TOTP standard as major authenticator apps
- Concentrates 2FA secrets inside a messaging app account
- Single-developer/open-source project, not a dedicated security company
