Instant PhoneCheck

Verification as it should be — instant and invisible

A smooth and seamless onboarding experience is the difference between a user and could've-been-a-user. No apps to download, no context to switch, no SMS to wait for, and no PINs to mis-type. Impenetrable security with a zero-friction user experience, so you can add 2FA without friction or go passwordless with confidence. It's the future of mobile identity verification, today.

Blazingly fast

Blazingly fast

Signing up with traditional identities takes minutes — when they work. Instant PhoneCheck verifies mobile numbers in seconds so your users spend less time waiting and more time using your app.

Delightful UX

Delightful user experience

Make security easy and painless. Whether you are verifying phone numbers as an additional factor or the only one, let the spotlight be on your app's UX, not on the means of verification.

No room for errors

No room for errors

An SMS has no delivery guarantee - many never arrive. When users do receive them, they can mis-type PINs or, worse, type them into a malicious site. Instant PhoneCheck protects your users from all these errors.

in-band and turnkey

In-band and turnkey

Instant PhoneCheck is the only verification product that works entirely in-band and is turnkey, not a series of disjointed steps. All other means of verification send the user out of your app, leading to abandonment and drop-offs. With Instant PhoneCheck the user never leaves your app, and the entire verification happens seamlessly. Fewer dependencies, better security and a better experience.

Real-Time Security

Instant PhoneCheck verifies the mobile data session created by a user's SIM card. It's a check of possession that can't be hacked, so spammers can't create fake accounts and there is no information to phish from unsuspecting users. Be certain the user of your app has the phone number you expect. Say goodbye to fraud and fake accounts, for good.

Invisible — Zero user input

Instant PhoneCheck whizzes your users through phone verification so you can convert every intentful user. Since there's no action necessary, you can craft amazing onboarding experiences. Whether you're building a new app and want a blazingly fast, passwordless onboarding, or considering adding 2FA to your app and worried about introducing friction — add security, not friction.
