Invalid rest password key

I created 2 custom pages: login and lost password.
I tested reset password received the email but I disregarded it and tried to log in.
Till then I receive an error message when I log in : invalid reset password key ( it is my translation of the message I receive in French: Clé de réinitialisation du mot de passe invalide ).
Somewhere there should be an info that keeps the fact I asked to reset the password.
But normally if I don’t react to the email with the reset password link, I should be able to log in as before
