Although it can be inconvenient, the two-factor authentication is the easiest and best way to keep your accounts from getting hacked. Whenever you log into an account from a new device, it will send an email or a text with a code that you input with your password.

Short of a fingerprint reader, two-step verification (aka two-step authorization) may be the single best way to protect online accounts.

2-Step Verification

If you're not already using 2-step verification, now is the time to enable it.

Two-factor authentication just shouldn't be optional anymore

This gives your users the option to increase the level of security to their account and help prevent unauthorized access.

Two-factor authentication, commonly abbreviated as 2FA, is any form of verification that requires two factors, like withdrawing money from an ATM using both a bank card and its PIN.
