“After 20 March 2023, we’ll now not allow non-Twitter Blue subscribers to make use of textual content messages as a 2FA technique. At that point, accounts with textual content message 2FA nonetheless enabled may have it disabled.”
Based on Twitter’s account safety report, which incorporates knowledge between July 2021 and December 2021, solely 2.6% of customers use two-factor authentication. Of these customers, 74.4% use SMS 2FA, 28.9 use an authenticator app, and 0.5% use a {hardware} safety key.
Elon Musk stated they’re making this transformation as they lose $60 million yearly on pretend 2FA SMS messages.
Musk later backed up this coverage change, stating that authentication apps “are way more safe than SMS,” possible referring to the danger of SIM-swapping assaults on cell units.
SIM swapping assaults are when menace actors take management of a goal’s cell phone quantity by tricking or bribing the provider’s workers to reassign the numbers to attacker-controlled SIM playing cards.
This allows the menace actors to make use of the telephone quantity on their very own units, obtain the sufferer’s SMS texts, together with SMS multi-factor authentication (MFA) codes, or log into accounts that use a telephone quantity as a part of the credentials.

If a menace actor positive aspects entry to your credentials, they won’t have entry to the code generated by your cell app and thus will not have the ability to log in.
The drawback with authenticator apps is that in the event you lose your telephone, you additionally lose entry to your 2FA codes, making it troublesome and time-consuming to regain entry to websites.
However, Microsoft Authenticator and Authy embrace the power to again up your 2FA settings to the cloud so as to restore your 2FA settings in the event you lose or wipe your system.
Therefore, both app is a superb alternative as your authentication app.
If utilizing Authy, although, ensure to disable the ‘Allow Multi-device’ setting when not transferring codes to a different system, as in case your telephone quantity is stolen, it may probably be used to entry your Authy account.
Regardless of the authentication technique you might be utilizing, Twitter’s safety report exhibits that far too many individuals will not be securing their accounts with 2FA, despite the fact that it will increase the safety of your account.
It is strongly suggested to allow 2FA on all on-line accounts you employ, together with Twitter, and to make use of an authenticator or a {hardware} safety key, because it’s finally safer.
