About Authenticator

<b>N.B</b> According to a "disclaimer" on the website, the Current Version of the
Android app is now proprietary and it isn't clear whether the source code
repository will be getting any more updates.

This can be used with non-Google apps that support it , but the most common use
will be to login to Google or other accounts in a web browser. You will probably
need https://f-droid.org/packages/com.google.zxing.client.android to be installed, though for some
accounts it may be possible to type in keys.

The Google Authenticator project includes implementations of one-time passcode
generators for several mobile platforms, as well as a pluggable authentication
module (PAM). One-time passcodes are generated using open standards developed by
the Initiative for Open Authentication (OATH) (which is unrelated to OAuth).

These implementations support the HMAC-Based One-time Password (HOTP) algorithm
specified in RFC 4226 and the Time-based One-time Password (TOTP) algorithm
specified in RFC 6238.
