Drag & drop OTP authentication provider|

An OTP is a dynamically generated set of numbers or letters designed to grant users one-time access to an application. These codes can be sent via email, SMS, or messaging services like WhatsApp. An OTP authenticates users through "proof of possession", which is usually their device like a laptop or phone.

OTPs are familiar to users, which reduces cognitive load and friction. They are also more secure than passwords, either as a replacement or as an MFA addition.

While OTPs are more secure than passwords, they are susceptible to threats like SIM swapping and man-in-the-middle attacks. Since OTP delivery depends on a third-party provider, it also contributes to rising costs, especially at large traffic volumes.

If your users' phone is their primary device, TOTP authenticator apps and passkeys are two well-known and strong OTP alternatives. Authenticator apps create a bit more friction but are more secure than OTP. Passkeys are even more secure and also provide a seamless end user experience if implemented properly.
