Asterisk - 2FA Authenticator

Asterisk is a powerful and elegant two-factor authentication code generator.

Compatibility
Asterisk is compatible with industry-standard methods used by most websites (TOTP and HOTP), and also provides support for Steam Guard and Yandex Key. In addition to account compatibility, Asterisk supports importing accounts from Google Authenticator.

Adaptive
Asterisk can be installed on Wear OS. And it supports the Android widget. Ready to be accessed anywhere, codes simply live on your wrist and home screen.

User-friendly
Asterisk is easy to use, allowing every user to get started effortlessly. You can set category for each account to improve efficiency while keeping account data organized.

Continuity
Asterisk supports data synchronization across devices (via WebDAV). You can not only backup accounts to cloud, but also access them on different devices.

Secure
Asterisk supports AES-256-CBC encryption, keeping your account data safe. You can also unlock Asterisk with biometrics to save time. Asterisk only accesses the Internet when performing data synchronization, and it only communicates with the server you set.

Elegant
Asterisk is designed with Material You and built with modern technology to seamlessly integrate with the Android system. Additionally, it allows customization of its appearance. Just say goodbye to those authenticators with outdated designs.

Simplicity
Asterisk does not include any unnecessary content and occupies minimal storage space. No need to tolerate the bloated size of other authenticators anymore.
