Twitch phone verification and two-factor: what to know
In short
- Twitch lets several accounts share one verified phone number.
- You can stop new Twitch accounts being created with your number in account settings.
- Twitch says VoIP numbers and landlines don’t work for two-factor authentication.
Twitch uses a phone number to verify accounts, for two-factor authentication, and to help you find your accounts.
Several accounts, one number
Twitch lets you link more than one account to the same number. Its account recovery page can text you a list of every account linked to a number.
Stopping new accounts on your number
In your account settings, turning off additional account creation by phone stops anyone making new Twitch accounts with your verified number.
Two-factor authentication
Twitch says VoIP numbers, such as Google Voice, Skype or WhatsApp numbers, aren’t supported for two-factor authentication, and nor are landlines. Our guide to why apps reject VoIP numbers explains why.
Using a one-time number
A number from ReserveSMS receives codes for 20 minutes only, so don’t make it your two-factor number: use an authenticator app for that. Ours start at $1, and the money goes back to your balance if no code arrives. Get a number for Twitch.
