Multi-factor authentication is one of the most effective ways to protect your accounts.
Why MFA matters
Even if a password is stolen, MFA blocks attackers from signing in without the second factor. BTS requires MFA on all managed business accounts.
How to set it up
After signing in, look for the security or 'Additional verification' settings. Choose an authenticator app as your primary method and add a backup such as a phone number.
Lost your second factor?
