Is Two-Factor Authentication supported?

Yes. If you have a valid plan subscription you can enable it in the account settings.

You have to set up SMS and email verification for two-factor authentication. You can set that up by verifying a phone number and a email address of your choice.

After enabling two-factor authentication you will receive a text message with a verification code on your phone when you sign in.

If the text message doesn't arrive on your phone you can request that the code is being sent to your email address that you did set up for two-factor authentication.
