This app generates two factor authenticator codes and can be used with almost any website that supports two factor authentication, like Google, Dropbox, GitHub and many more.
Features:
• Support for all websites that use the HOTP/TOTP based two factor authentication
• Add entries by scanning a QR-code or entering a code manually
• Customize the color of entries and add an icon image from your storage to easily distinguish entries
• Re-order items by dragging the item from the icon
• Export all the entries to an encrypted file so you can back up your codes and restore them by importing the file again
• Open source: https://github.com/wilco375/1-2-Authenticate
Note: the free version is limited to 8 entries. If you want to support the development of this app you can buy the Pro version and add unlimited entries.
