DISCLAIMER: I am not a security expert so I wouldn't necessarily recommend you to use this for your actual passwords. This project simply exists on my github so that I can use it across many devices.
totp is a TOTP (Time-based one-time password) authenticator as specified by RFC6238 and is made to work well with other programs, in that way it is almost homogeneous with "pass(1) - the standard unix password manager".
To use totp you will either need to pipe the data to totp or specify a file with your secrets (using the -f flag). The input should contain two tab-separated fields:
- The first field is an identifier for what the temporary password will be for. This is up to the user to decide and will not affect the outcome of the secrets. Note that the field is truncated at 25 characters.
- The second (and last) field is the secret key.
I recommend keeping a GnuPG encrypted file with all the secrets on disk and adding a alias in your shell to use totp:
totp='gpg -qd $HOME/.totp.gpg 2>/dev/null | (which totp)'
