Ubuntu Authenticator

Ubuntu Authenticator can be used for the two factor authentication for Ubuntu SSO and other OATH-TOTP compliant two factor auth sites. It also features easy configuration by scanning QR-Codes using the camera.

Only event based (counter) authentication tokens are supported at present.

Installation packages can be downloaded from the Ubuntu App Store.

    Hi, I installed Authenticator on my Aquaris E4.5 Ubuntu Edition.

    I have some questions…
    1 – Do I have to make several accounts, or is it sufficient to make just one?
    2 – Where do I find the 32 or 64 digits key? Can I just invent one?
    3 – Is it possible to delete or change (edit) an account?

      Erm… You’ll get the key from the service where you like to authenticate to. Usually in form of a QR Code that you can scan with the app.

    On Nexus 5, your application just gives me a white screen. Can I do something to help you debug it?

    • Michael says:

      yes, send me the log :)

      You can use the logviewer app from the store if you don’t know how to get it manually from the device.

    I go to
    but how to view the code ?
    – there is no link for either browsing or downloading the source code?
