trouble with wp-Login.php to reste password procedure

In WordPress, there is more than one way for Rsetting Your Password .

Ok, thank you for this page

Thiw website is for an association, I do not want change password for all members. I need to have a automatic procedure.

In the email, I saw wthat I have not User Login in where it should be.
In the Url I saw that I have not Login value but only Key key=Ss7l8x9WUbnOmM6f680h&login=

Do you think it come from my current installation for development on wamp server ?

If yes, I will try later on my production server.

Dear,

With the lostpassword link I always get i wrong link with this error message:
“Your password reset link does not appear to be valid. Please request a new link below.”

I get link
https://monsite.com/wp-login.php?action=rp&key=0hk18C06p2GfQbIiWVrG&login=
but not working

I have to add the user login at the end of link to get it works.

How can I solve the mail generation ? or Url generation problem ?
Its looks like a problem in link and mail generation for the reset password form.

Have you tried:
– deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
– resetting the plugins folder by FTP. Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder (if you have created such folder). The easiest way is to rename that folder to mu-plugins-old.
– switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins).
– If all the above steps do not resolve the issue, then try MANUALLY updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old wp-admin and wp-includes folders and files on your server before uploading the new ones. Please read the Manual Update directions first.
– Backup: If you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong. You can never have enough backups!
