Hi, I am trying to make forgot password script on www.thewallclone.com and I do not worry about it, because it was successful. In this post we are going to learn how to implement forgot password system on our web application, recover lost password from account using php, on this forgot password system we have form for account verification that will help us to create a new password for that account.




First, we are to verify either the user email address to send reset link for an opportunity to create new [fresh] password. The Password recover email has a link to the page where we can reset password.

How does password recovery work ?

Password Recovery help you recover lost and forgotten password or an opportunity to create new password or reset password.
E-mail verification is use to send a reset link to the user. Generate a unique random code, tie it to the user account, probably set an expiration time this is optional and store them into the database. Then generate a unique link and mail it to the user email address during registration.
So, for the verification aspect. When the user clicks the link, they will have the following data at your disposal: the email, and the token (a unique random code). That should be enough to do verification.  This part do the following checks:
  • Is the email valid?
  • Is the email-token binding valid?
  • Is the token expired? (Optional)
  • Has the token been used?
  • Is the token field empty?

If all checks out, allow the user to provide a new password/verify their email. No matter success or failure, it is very important to invalidate the token after use.

    With havin so much content and articles do you ever run into any problems of plagorism or copyright violation?
    My site has a lot of unique content I've either created myself
    or outsourced but it appears a lot of it is popping it up all over the internet
    without my agreement. Do you know any solutions to help stop content from being ripped off?

    I'd genuinely appreciate it.

    First of all I want to say terrific blog! I had a quick question that I'd like to ask if you
    don't mind. I was curious to know how you center yourself and clear
    your head prior to writing. I've had difficulty clearing my thoughts in getting my thoughts out there.
    I truly do take pleasure in writing however it just seems like the first 10 to 15 minutes are usually wasted simply just trying to
    figure out how to begin. Any ideas or tips? Kudos!
