# TOTPgen
A simple one-time password generator using the `TOTP/HOTP` algorithm for two-factor authentication (2FA). The program works both from the `*.tar.gz` archive (with user rights, see Releases) and from the `rpm package` (root, pkexec/kdesu).
**Requires:** oath-toolkit **>= 2.6.7**, polkit, gtk2, qrencode, zbar, tar, gnupg2
**Work directory:** ~/.config/totpgen
**Important:** for the program to work correctly, the time on the local computer must be accurate.
After launch, create an entry by clicking the `+` button. Enter the Record `Name`, the secret `Key` that was issued to you on the site and click the `Apply` button. Now click the `TOTP` button and receive a password to enter into the site; it will be copied to the clipboard. Depending on your requirements, you can double-click on the entry (or press `F4` on your keyboard, see tooltips) and change the parameters.
Starting with `v0.2`, TOTPgen can take `TOTP/HOTP` parameters from a **QR code on the screen** (button with an `eye`). In this case, a record is created automatically. The main thing is that the QR code is fully visible on the screen.
TOTPgen understands 2 secret key formats: `base32` and `hex`. The default is HASH=SHA1, DIGITS=6 (RFC 6238), the new password generation step is 30 seconds. The correctness of the key can be checked, for example, in the terminal:
```
oathtool --totp 'your_hex_secret_key'
oathtool -b --totp 'your_base32_secret_key'
```
If a `TOTP/HOTP` password is not created, enter the correct secret key. If the site does not accept a password, check the time on your computer.
