A substantial proportion of your customers' email + password pairs have been leaked before they sign up with you. Email and phone are already paired from data brokers, you don't need the dump.
A majority of SaaS providers and banks fail to check for previously leaked creds. Many of the same ones that think SMS is "perfectly good".
- patmcc 3y agoIs your bank one of the ones that uses email addresses for usernames? Because that's a great way to make it much easier for attackers to match up leaked creds. Consider switching to a (chosen) username or card number or something. If your username is quickly matched to a phone number (or email address) it makes phishing (or account takeovers) much easier.
