Generate OTP

<?php

use Ichtrojan\Otp\Otp;

(new Otp)->generate(string $identifier, string $type, int $length = 4, int $validity = 10);

• $identifier: The identity that will be tied to the OTP.
• $type: The type of token to be generated, supported types are numeric and alpha_numeric
• $length (optional | default = 4): The length of token to be generated.
• $validity (optional | default = 10): The validity period of the OTP in minutes.

Sample

<?php

use Ichtrojan\Otp\Otp;

(new Otp)->generate('michael@okoh.co.uk', 'numeric', 6, 15);

This will generate a six digit OTP that will be valid for 15 minutes and the success response will be:

{
  "status": true,
  "token": "282581",
  "message": "OTP generated"
}

Validate OTP

<?php

use Ichtrojan\Otp\Otp;

(new Otp)->validate(string $identifier, string $token)

• $identifier: The identity that is tied to the OTP.
• $token: The token tied to the identity.

Sample

<?php

use Ichtrojan\Otp\Otp;

(new Otp)->validate('michael@okoh.co.uk', '282581');
