About
Otter is a two-factor authentication app, 100% offline: your TOTP and HOTP codes are generated on the phone, from keys that stay there. No account, no cloud, no network requests. Keys encrypted with AES-256-GCM, behind biometrics or a PIN code. Free, no ads.
Testers: a demo account to scan awaits you at otter.foohx.com, no need for a real second factor. Keep the app for a few days and let me know what's not working.
