You aren’t just protecting yourself with Account Takeover Protection- you’re protecting the people you know from your accounts as well.
Things like ACH wire transfer frauds and phishing occur when your accounts have been compromised, and bad actors impersonate you to harm the people you know.
To prevent this from happening, you need security in layers. Account takeover is integrated with SSO, Conditional Access, and MFA. All of these things work together to prevent there from being backdoor ways to access your information.
