Enhance security and verify users with SMS OTP

SMS One-Time Passwords (OTPs) add another valuable layer of security to standard user-generated passwords and login information.

With SMS OTP, users receive a single-use code via text that is completely unique and expires after a short time. Only the user can access this code on their phone, which they then need to input before proceeding.

Unlike static passwords that are vulnerable to breaches and unauthorised access, OTPs are uniquely generated at each login attempt, ensuring that only authorised users gain access.
