emacs-TOTP implements Time-based One-time Passwords (TOTP) like specified in RFC 6238)

Setup

Until released on MELPA:

(add-to-list 'load-path "/path/to/emacs-totp")
(require 'totp)
;; if you want the authenticator widget
(require 'totp-widget)

Usage

The command totp-copy-pin-as-kill interactively prompts for account names. Non-existing Accounts/Secrets will be added to your configured Emacs auth-source and will be available in the completing-read history in it will be used at the next invocation.

Secret input format

totp supports reading secrets in HEX and multiple base32 variations:

Some providers use non-standard base32 encodings (interleaved whitespace and missing padding characters) like: 6BQA C4L3 O2FZ YNKR 6H7H IFFX 64GG SZZK SDEO FMV4 KVKI ASYE 65QA

Widget
