You can set up 2-factor authentication if you created an account with your email and made a password. If you signed up for Spritz through your Google account, an additional 2FA is unavailable. This is because you already have a 2-factor authentication set up through your Google account.
Here is how to set up 2FA:
Head to your profile and click on “set up 2FA” in the prompt at the bottom
Scan the QR code with your authenticator app to add your Spritz account
Enter the code it gives you in the app
Once you enter the code, you’re done!
