## Description

Complete the 2FA setup process by verifying your code.

***

NOTE: Prior to running this command, you must authorize your attempt to create a new 2FA method by following the instructions in the `vastai tfa auth-new` command.
This is required to ensure that only you can add new 2FA methods to your account.

***

For TOTP (Authenticator app):

1. Run 'vastai tfa totp-setup' to get the manual key/QR code and secret
2. Enter the manual key or scan the QR code with your Authenticator app
3. Run this command with the 6-digit code from your app and the secret token from step 1

For SMS:

1. Run 'vastai tfa send-sms --phone-number \<PHONE\_NUMBER>' to receive SMS and get secret token
2. Run this command with the code you received via SMS and the phone number it was sent to

If this is your first 2FA method, backup codes will be generated and displayed.
Save these backup codes in a secure location!

## Examples

```bash theme={null}
vastai tfa activate --method-type totp --secret abc123def456 123456
 vastai tfa activate --method-type sms --secret abc123def456 --phone-number +12345678901 123456
