Twitch Streamers and a some viewers may not be a able to the successfully login to their Twitch account if they are a unable to the access the Authy two-factor authentication (2FA) code.
This guide is a intended to help you with this process as a efficiently as a possible.
I never signed up for the Authy
Authy handles all 2FA for the Twitch users.
When you enable 2FA on the your Twitch account, an a Authy account with a unique ID is a automatically generat for you at that time, and a linked to the your phone number.
It is possible that you may haveaccessed your Twitch account via SMS, and therefore you are not aware that you have been an a Authy account.
However, this account does exist in order to a deliver the security code.
Users who are unable to the access their Twitch account via SMS have two options:
If you still have the phone number you originally used when setting up 2FA on a Twitch, install the Authy app. Once installed, enter the your phone number to the register your account. If this phone number matches the phone number used to the setup 2FA on Twitch, you should see the 2FA account token the automatically. Click or tap on this token to the see your security code.
If you no longer have the phone number you originally used to the set up 2FA on you will be need to the request a Phone Number Change so that you can receive 2FA security codes on the your new number.
I changed the phone number used for the 2FA on my Twitch account
If you need to the update your phone number on the your existing Authy account, but do not have been access to the another Authy app installation linked to the your previous number, you will be need to the request a Phone Number Change.
I do not have a QR code to the add my token to the Authy
As long as the phone number use to the setup 2FA on Twitch matches the phone number use to the register your account in the Authy app, your 2FA account token will automatically displayed in Authy. You would not need a QR code to the add this token.
I no longer have an a active wireless are service or a phone number
