Open Two-Factor Authenticator Extension

Open Two-Factor Authenticator aims to provide an open-source two-factor authentication to browsers and Android devices with synced storage.

By using this extension, you can have your encrypted keys stored in the browser's synced storage. This allows you to sync them across multiple devices. This extension uses the public key/private key method to encrypt stored data (SHA-256).

Currently, Open Two-Factor Authenticator supports Firefox on Desktop, Firefox on Android, Chrome, Edge, and Opera browsers. Standalone Android implantation is still in progress.

Features:
1. Stores secrets securely using AES-CBC encryption.
2. Does not store passwords
3. Does not have any server-side activities whatsoever
4. Uses synced storage, so secrets are securely shared between multiple devices.
5. Supports custom number of digits and custom validation period

Esther Z (ID: 000000b4a3ebbcc6) Voted 3 ★ - Updated 02/12/2021 Werkt prima. Onhandige is, dat er geen optie bij zit om de code te kopiëren. En omdat het schermpje over je scherm opent waar je code moet invoeren, is enige optie de code te selecteren, rechtermuisknop en dan code kopiëren. Op zich prima, als er daardoor niet een spatie in het midden van de code wordt meegenomen (code bestaat uit 2x 3 cijfers). Voordat ik dat doorhad...Nu moet ik die spatie iedere keer verwijderen na het plakken. Room for improvement!
