Basic Steps.
1. Database.
The first thing you need is a database to store user information. You can use MySQL, for example, to create a table that contains information such as the username, email address, and encrypted password.

CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(50) NOT NULL,
email VARCHAR(100) NOT NULL,
password VARCHAR(255) NOT NULL
);
2. Generate Reset Token.
When a user requests to reset their password, it is a good practice to send them a unique link containing a token. This token will be used to verify the authenticity of the user when resetting the password. You can generate a unique token using functions like uniqid().

3. Password Reset Page.
Create a page where users can enter their email address to start the password reset process. Upon submitting the form, an email will be sent with the link containing the unique token.

4. Token Verification.
When the user clicks on the link sent by email, they are redirected to a page where they must enter a new password. Verify the authenticity of the token before allowing the user to change their password.

5. Update Password in Database.
Once the token has been successfully verified, it allows the user to enter a new password and updates the password stored in the database.

Implementation in PHP.
Below is a basic example of how you might implement some of the steps mentioned in PHP.
