Stillcode › Two-factor authentication › Twitch
Twitch publishes software of its own for this and also takes an open authenticator code. What choosing either one commits you to, and what happens when the phone holding those codes is gone.
These are the second factors Twitch offers on twitch.tv. Which ones you
see can depend on your plan and your country;
what each of the seven actually costs you is set out once.
| Method | What it is | |
|---|---|---|
| Authenticator app (TOTP) | Supported | Computed on your own device; nothing is sent to produce it. |
| The service’s own app | Supported | Software this service publishes; it works, and only here. |
| SMS text message | Supported | Texted to your number, so your carrier is part of the lock. |
| Hardware security key | Not offered | A physical key you tap; the one option phishing does not beat. |
Twitch's own caveat, as recorded in the directory: To activate two factor authentication, you must provide a mobile phone number.

Twitch offers both SMS and an authenticator app. They are not equivalent — a texted code depends on your mobile carrier and survives no longer than control of your phone number, while a generated code never travels. If both are enabled, the account is only as strong as the weaker one, because an attacker picks.
Twitch also offers a prompt through software it publishes itself. It works, and it works only here: an account secured that way ties you to that software on whatever device you happen to be holding, which is the trade-off an open standard like TOTP exists to avoid.
Of the fifty services on this site, nine publish software of their own as a second factor,
and Twitch is one of them. Two of the fifty accept exactly this combination, so the same
decision comes up on one other
service here. No other service here carries the entertainment label at all.
The directory files Twitch under entertainment, records three of the seven second
factors it tracks, and points at instructions published at
help.twitch.tv/s/article/two-factor-authentication.
Twitch's own instructions: Twitch — two-factor authentication — linked, never copied, because a stale menu path here locks people out.
Twitch publishes no dedicated page for losing your second factor, which in practice means the route back is ordinary account recovery: proving who you are to support, on their timetable.
