nOTP can help you add a layer of security to apps without adding complexity for your users.

Resetting password

Instead of sending codes via email or SMS, nOTP is a hassle-free way to verify users before password resets.

Passwordless logins & authentication

Users do not have to remember passwords and can simply be verified using nOTP every time they log in.

Prevention of spam

Instant verification allows you to stop spam registrations and avoid fake users from signing on.

AppToApp Calling

Easily integrate voice calling capabilities inside any app you build. Here’re some of its benefits.



Every interaction is encrypted and all the sessions are secure. Built with an enterprise first focus.

Cost Effective

With data plans becoming cheaper than voice plans, this is a huge cost saving for both the company and their clients.


Since the calls are not routed via any phone number, the customer’s information remains safe and private.


Since all the conversations are contained within the app, they can easily be tracked for all business purposes.
