Twitch now offers two-factor authentication (2FA) to protect your account from unauthorized logins. 2FA requires two different methods of verification to log in to your Twitch account: your password and your mobile phone. If your password is compromised, your account will be inaccessible without the unique code sent to your phone.
This article is intended to provide guidance on the usage, configuration, and troubleshooting of Authy 2FA. 2FA is 100% voluntary. If you do not enable it, you will still be able to log into Twitch with your password as usual. However, if you would like some additional protection, it is highly recommended for you to enable 2FA.
Enter the verification code you receive via text message or Authy (if you are an Authy user)
Here are some other best practices to keep in mind:
Install Authy on your regular phone and not a “temporary” phone, landline phone, or VOIP/Google Voice. Using a more permanent phone number is recommended because you are limited to two number changes every three months. If this allowance is exceeded, you would be locked out until the time remaining in the three month cooldown has passed.
Document the phone number and email that was used to set up your account. If you are ever locked out of your account, you will need this info to gain access.
Install the Authy Chrome app or Mobile app on at least one device other than your phone. In the event that your phone is lost, this will provide another means of accessing the account and submitting easy, self-service requests for phone changes.
If you are a broadcaster, ensure you get all of your moderators to enable 2FA. This is to protect your chatroom from compromised moderator accounts.

How To Request A Phone Change
If you have access to your old/previous phone associated with your Authy account:
Open the Authy application on your old phone
Tap Settings in the upper right hand corner
Click the phone number
Enter the country code and new phone number in the New Phone Number field
Tap Change Phone
Verify that the phone number has in fact changed on your Account page
If you do not have access to your old/previous phone associated with your Authy account, but you do have either the Authy Mobile app or the Authy Chrome app installed on another device:
Open the Authy Chrome app
Tap Edit next to your phone number
Enter the new number
Tap Save next to the new phone number
If you do not have access to your old/previous phone associated with your Authy account and do not have the Authy Mobile app or the Authy Chrome app installed on another device, a phone change request will have to be made through the Authy website. This can take up to 48 hours to complete.
How To Merge Multiple Accounts On One Phone
Merging allows you to consolidate multiple accounts under a single phone number. It is performed the same as a Phone Change Request using the procedure above. The only difference procedurally is that you will receive an email confirming you wish to do so as part of the process.
For Apps That Use Our Old Authentication Flow
If you are using an app that uses our old authentication flow like El Gato or Wirecast, you will need to append your 2FA token to your Password when signing in.
For instance, if your password is mypassword and the 2FA token is 123456, you would sign in with mypassword123456.
