Using SMS Verification for Two-Factor Authentication

SMS verification sends a one-time code to your phone number when signing in. This option is convenient, but less secure than an authenticator app.

How SMS 2FA Works

  1. Select SMS as your 2FA method

  2. Enter your phone number

  3. Sonikit sends a verification code via text message

  4. Enter the code to complete sign-in


When SMS Codes Are Sent

  • During login

  • When verifying sensitive account actions

  • When switching devices


If You Don’t Receive a Code

  • Wait up to 60 seconds

  • Check your signal and spam filters

  • Request a resend

  • Confirm your phone number is correct


Security Considerations

SMS verification:

  • Depends on carrier delivery

  • Can be delayed

  • Is vulnerable to SIM-swap attacks

👉 For maximum security, we recommend using an authenticator app.


Switching Later

You can switch from SMS to an authenticator app at any time in Account Settings.
