otp plugin

This plugin allows you to create one-time passwords using oathtool, able to replace MFA devices. The oathtool key is kept in a GPG-encrypted file so the codes can only be generated by a user able to decrypt it.

To use it, add otp to the plugins array in your zshrc file:

plugins=(... otp)

Provided aliases:

  • otp_add_device: creates a new encrypted storage for an oathtool key and stores it on the disk. For encrypting the key, it will ask for a GPG user ID (your GPG key's email address). Then the OTP key needs to be pasted, followed by a CTRL+D character inserted on an empty line.

  • ot: generates a MFA code based on the given key and copies it to the clipboard (on Linux it relies on xsel, on MacOS X it uses pbcopy instead).

The plugin stores its internal files in $OTP_HOME, which can be set in your zshrc. If $OTP_HOME is not set it defaults to either $HOME/.otp or $XDG_DATA_HOME/otp, depending on whether ~/.otp already exists, or whether $XDG_DATA_HOME is set.
