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.
So what is two-factor authentication and what should you do to secure your social media account?
Two-factor authentication (2fa) is a second step once you have logged into an online account with a password to prove you are who you say you are. It is an extra layer of security so if your password is compromised, it will be slightly harder for someone to access your account.
For authenticator apps and SMS two-factor authentication, you are sent or provided with a number or numbers for you to enter back into the website.
Most online services like social media platforms, banks and ones used in workplaces now either require or strongly recommend people use 2fa on their accounts.
While the company is correct that SMS-based authentication is not the best, it is not widely considered to be a money-making venture for those who misuse it.
Although no method is foolproof, SMS is much easier to compromise.
People can use what is called sim-jacking or sim-swapping to take over your mobile number which can then be used to access your account. This is done by convincing or forcing a telecommunications company to port your mobile number over to a new sim card.
Some countries, including Australia, have introduced rules requiring telecommunications companies to properly verify who someone is before allowing them to port a mobile number to a new provider.
When you set up 2fa via the Twitter app on your mobile , it will prompt where you can authenticate.
