There are many people to sign up in many websites. Unfortunately, most of them use the same password in many sites. they think the same password is good choice because it will make the easy in next login. Of course, it is the fault decision to use same password in the many websites.
There are many way to save our account, one of them is the 2FA using. As the second security layer, it is important to save and keep our online account from the thief. I think most of the online websites which have the members user like mailing provider, trading, online shopping, etc. They will give the 2FA options in the security setting to user member as the second security layer except the password.
The 2FA option will give the barcode and the code text that can be used to activate the 2FA security in their account. But, we have to keep and memorize our QR code in the save place or re-write the manual code given in a piece of paper.
We can use many application to support this 2FA security like google authenticator, authy, 2FAS, etc.
