How to Enable Two-Factor Authentication Without SMS on Twitter for Free

Ever since Elon Musk bought Twitter, Twitter has seen some big changes. Recently, Twitter launched a subscription service for blue ticks next to profiles. Twitter is also offering several special features with this subscription to make their new subscription service more attractive to users. Several services that were previously available for free are now included in this premium service of Twitter. One such feature is TwoFA or Two Factor Authentication SMS for security. Earlier this service (SMS based two step verification facility) was available for free to keep Twitter account secure.

Even if you log in to Twitter with a password on the 2FA service, Twitter usually sends you a special code or OTP each time via a text message to your mobile. Only by inputting this code can you successfully login to your account.

These two layers of security make it difficult for hackers or cybercriminals to log into someone else's Twitter account. Although Twitter has stopped the service of giving free OTP code through SMS, it is possible to get this code for free through another means. That is, two-level identity verification is possible.

Currently, Twitter has added the SMS or text to FA service as a perk of their $8 per month subscription. As a result, free Twitter users can no longer receive the TwoFA service via text SMS. However, Twitter still allows the use of other authentication methods for TwoFA. Today's post will let you know how you can get TwoFA service on Twitter for free.

SMS or text authentication is a very good and convenient 2FA authentication method but it also has some weaknesses. Many times criminals can easily take the OTP code from your number in case of SIM theft or mobile theft. Many cybercriminals can easily take over your SIM through a new type of attack called SIM swapping. Although this type of hacking is not very popular in our country. SMS TwoFA is not completely secure. So it might be a good idea for your Twitter account to use different authentication methods. This will make your account more secure and less likely to be hacked.

As of March 19, 2023, SMS TwoFA has been discontinued for all free Twitter users. 19th was the last day. For those who have SMS TwoFA enabled, TwoFA will be automatically turned off after this time.
