AuthMonster

Most two-factor authentication apps are built almost as an afterthought by big companies like Google and Microsoft, with a clunky, bare-bones experience. AuthMonster takes a different approach: we put user experience front and center, wrapped in a lovable brand starring Toki, your token-eating monster. Under the hood, you get painless migration from apps like Google Authenticator and LastPass, biometric locking, and a donation-based model instead of paywalled features."
