Multi-factor authentication made simple
The security of your users' personal information is critical—and so is your UX. Bandwidth's Authentication API helps you accomplish both missions quickly and easily.
Customizable codes and messages
Customize your authentication messages to balance security and ease of use —conveying brand and security. Create the right amount of security for your org by setting a code expiration timeframe that meets your unique needs.
Only pay for successful authentication
Don’t waste budget on unsuccessful authentication attempts. Whether because of wrong numbers or a missed message, you only pay for successful authentication using our API.
Use your own number for instant brand identity
Our Authentication API enables you to use your existing numbers to send one-time passcodes. This allows you to protect your brand equity by not sharing numbers with other businesses, creating a better overall end-user experience.
