Key file ~/.otpkeys

You can save your keys to ~/.otpkeys file using service=key format, for example:

$ cat ~/.otpkeys
aws=N5VEJBTUA553BYJTTTUGS3GANKVDECG62RHVIOV2FLYR5THC726ZOIOF4SQZZ5NV
google=QYDL7HS7LHPVKX7GGYKYIP3UEYOML2IENWYQD5NHYGETBZIRWWODKQWC3PRNQ3FO
facebook=ZBSLA3KGE4PEXCEGIJ57AKJLOHW2S3ABQNOOWZVV3HOO4Q3455BOG6BRNU5M2QK4

Then you can generate OTP, by running:

$ otp {service}

Example:

$ otp aws
443782

$ otp google
760698

$ otp facebook
009176

Auto copy OTP to clipboard (Mac OS X)

Add the following code at the end of your ~/.bashrc file (change path to otp if needed):

otp_func() {
  if code=$(/usr/local/bin/otp $1 2>&1); then
    printf "%s\n" "$code" | tee /dev/tty | pbcopy
  else
    printf "%s\n" "$code" >&2
    return 1
  fi
}
alias otp='otp_func'

Example:

$ vim ~/.bashrc
$ source ~/.bashrc
$ otp cloud
324982

At this point the above OTP should be in the clipboard.
