What is Aegis?

Aegis is a free, open-source Android application that stores and generates time-based and counter-based one-time passwords (TOTP/HOTP) for two-factor authentication. It encrypts your vault locally and never syncs data without your explicit consent. The app supports import from other authenticator apps, QR code scanning, and offers backup/restore via encrypted files. Community-driven development ensures regular security updates and feature enhancements.
