If you can no longer identify yourself to your account, click here, How to recover my forgotten password?
To delete your account from your personal space, open the drop-down menu at the bottom left of your screen - under your name - then click on General Settings.
Then go to My Account :
Finally, directly modify your password by clicking on Edit to the right of Password.
A new window opens.
Enter your old password first, then click on Next.
You can now write your new password!
It is mandatory to create a password longer than 8 characters. And for more security we advise you to use numbers, upper and lower case letters and even special characters.
It was not that difficult, but we know that the hardest part of a password is not creating it, it's remembering it.
