O Twitter is displaying a message that tells non-paying Twitter Blue users about withdrawing their two-factor authentication (2FA) benefit via SMS message. In the application, there are three ways to use authentication, including via SMS message, offering the option to use authentication apps and physical security keys.
Twitter will charge for two-factor authentication via SMS
Note that Twitter has only referred to two-factor authentication (2FA) via SMS message as an exclusive benefit for Twitter Blue users for the coming month. Although some users thought this decision was bad, the company made it thinking about how flawed the protection using SMS messages is. According to company data, 74.4% of the 2.6% who use 2FA use SMS messages.
As you can see in the message above, Twitter has given users 30 days to disable two-factor authentication (2FA) via text message (SMS) if they don’t subscribe to Twitter Blue. However, it is possible to use the other two authentication options: via the multi-factor authentication (MFA) application and via the physical security key. Oficina da Net gave some tips in its article on what multifactor authentication is, where some interesting apps to use were recommended.
What is the physical security key?
The physical security key is a multifactor authentication method (MFA) that are literally with the user, as they are objects that are used as keys to login to various online services. In order to be able to break into an account of someone who uses this form of protection, it is necessary to literally steal the object or make a perfect copy of it, without the owner noticing, as it is still possible to block the use if he becomes aware.
