Twitter is ending free SMS two-factor authentication. So what can you use instead?

Receiving login codes via text message is much easier to compromise. Using authenticator apps or even a USB are preferred alternatives

On the weekend, Twitter announced that from 20 March, people who haven't subscribed to Twitter Blue will have two-factor authentication via SMS disabled.

Twitter has recommended people use third-party apps or a security key instead, but for the overwhelming majority (74.4%) of the 2.6% of active Twitter users who use SMS as their method of authentication, it will mean they have a month to switch or potentially lose protection.
