Establish more with Authentication API

Use alternative passwords with single-use codes sent over SMS, voice or push. Phone number identities let you connect your users with their contacts.

Authenticate unique phone numbers to prevent bots, spammers, and card testers more effectively than captchas or email verification.

Allow an additional second factor to authenticate users without hardware costs or complex integration. Ensure global exposure and wide audience reach from day one.

Reset passwords in a secure manner by confirming users’ ownership of their phone number. Fastest solutions with less help desk or help center costs.

Apply out-of-band authentication on high-value transactions or when risk score crosses a threshold and eliminate manual reviews.

Balance user acquisition with compliance by phone verifying lower tier customers instead of onerous id verification for all users.
