Huge thanks to author. I use mintotp pretty much always I need to get token from "pass" stored secret.
Huh, have you heard of the popular pass(1) extension pass-opt[1]?
It allows one to get OTP secrets via a simple:
pass otp secretname # Add -c for clipboard, as usual
And because the OTP side is just a otpauth:// URL on a line of the GPG file, we can still use the rest of the secret for other things:
pass secretname -c
Real smooth!
