# pass-otp
A [pass](https://www.passwordstore.org/) extension for managing
one-time-password (OTP) tokens.
## Usage
```
Usage:
pass otp [code] [--clip,-c] pass-name
Generate an OTP code and optionally put it on the clipboard.
If put on the clipboard, it will be cleared in 45 seconds.
pass otp insert [--force,-f] [--echo,-e] [uri] pass-name
Insert a new OTP key URI. If one is not supplied, it will be read from
stdin. Optionally, echo the input. Prompt before overwriting existing
password unless forced.
pass otp uri [--clip,-c] [--qrcode,-q] pass-name
Display the key URI stored in pass-name. Optionally, put it on the
clipboard, or display a QR code.
pass otp validate uri
Test if the given URI is a valid OTP key URI.
More information may be found in the pass-otp(1) man page.
```
## Examples
Prompt for an OTP token, hiding input:
```
$ pass otp insert totp-secret
Enter otpauth:// URI for totp-secret:
Retype otpauth:// URI for totp-secret:
```
Prompt for an OTP token, echoing input:
```
$ pass otp insert -e totp-secret
Enter otpauth:// URI for totp-secret: otpauth://totp/totp-secret?secret=AAAAAAAAAAAAAAAA&issuer=totp-secret
```
Pipe an `otpauth://` URI into a passfile:
```
$ cat totp-secret.txt | pass otp insert totp-secret
```
Use [zbar](http://zbar.sourceforge.net/) to decode a QR image into a passfile:
```
$ zbarimg -q --raw qrcode.png | pass otp insert totp-secret
```
Generate a 2FA code using this token:
```
$ pass otp totp-secret
698816
```
Display a QR code for an OTP token:
```
$ pass otp uri -q totp-secret

## Installation
### From git
```
git clone https://github.com/tadfisher/pass-otp
cd pass-otp
sudo make install
```
### Arch Linux
`pass-otp` is available in the
[Arch User Repository](https://aur.archlinux.org/packages/pass-otp/).
## Requirements
- `pass` 1.7.0 or later for extension support
- `oathtool` for generating 2FA codes
- `qrencode` for generating QR code images
## Migrating from pass-otp 0.1
`pass-otp` has switched to storing OTP tokens in the
standard
[Key Uri Format](https://github.com/google/google-authenticator/wiki/Key-Uri-Format).
You'll need to edit any saved tokens and change them to this format. For
example:
```
$ pass edit totp-secret
```
Old format:
```
otp_secret: AAAAAAAAAAAAAAAA
otp_type: totp
otp_algorithm: sha1
otp_period: 30
otp_digits: 6
```
New format:
```
otpauth://totp/totp-secret?secret=AAAAAAAAAAAAAAAA&issuer=totp-secret
```
Note that the following default values do not need to be specified in the URI:
| parameter | default |
| --------- | ------- |
| algorithm | sha1 |
| period | 30 |
| digits | 6 |
