best practice to generate random token for forgot password
A common practice for generating a random token for a "forgot password" feature in PHP is to use the built-in functions random_bytes and bin2hex.
A common practice for generating a random token for a "forgot password" feature in PHP is to use the built-in functions random_bytes and bin2hex. random_bytes generates a specified number of cryptographically secure random bytes, and bin2hex converts those bytes to a hexadecimal string. The resulting token can then be stored in a database and sent to the user via email. An example implementation might look like this:
Example of using the built-in random_bytes() and bin2hex() functions to generate random token for forgot password in PHP
<?php
$token = bin2hex(random_bytes(32));
echo $token;This will generate a 64-character hexadecimal token.
It's important to also consider the token's expiration time and to check for token validity when the user attempts to reset their password. Store the token with an expiration timestamp in your database and invalidate it after use or expiration.
