Here at Circle, we want to make sure our customers feel secure. We protect both you and your data in a variety of ways to ensure a seamless and secure payment experience. 🔐
Storing Your Personal Information
AES 128-bit symmetric encryption & PCI Compliant
All personal and financial information is encrypted with two levels of AES 128-bit symmetric encryption. In other words, the data is encrypted using keys that are themselves encrypted using other keys, with separate key storage mechanisms for each layer. Circle is fully PCI-DSS compliant as a business.
Account Protection Features
Two-factor sign in, logout active sessions
Circle requires two-factor authentication when signing up and signing in, so even if your password is compromised there are reinforcements to help keep your information safe! (What is two-factor authentication?)
You also have the option to a) sign out of all of your current sessions on your devices if you lose a device or fear one of your devices was compromised and b) set send/cash out thresholds that require two-factor authentication.
