What was wrong
In Profile → Security → Change Password, the server dropped the passwords you typed before it checked them. Every attempt ended with "Failed to change password. Please try again.", whatever you entered, and your old password stayed in place. Nothing else about your account was affected.
What changed
- The form now changes your password when the current password is right and the new one meets the rules.
- When something is wrong, you see the actual reason: "Current password is incorrect", or the rule the new password misses (at least 8 characters, an uppercase and a lowercase letter, a number and a special character).
What to do
If you tried before and gave up, try again. Your current password is still the one you sign in with today.
