Embedded Wallets provides built-in support for email and SMS-based authentication, allowing users to log in seamlessly using a one-time passcode (OTP) sent to their email address or phone number. This form of passwordless authentication simplifies the onboarding process, removes friction for end users, and expands accessibility—especially in regions where social login options may be limited.
