Yes, there are!
We are continuously improving the security of our systems. One of the security measures we take is improving the passwords used for our service. We use a service called Have I Been Pwned? (or HIBP). This service collects data leaks. It has gathered billions of leaked account and password pairs. To improve your security we check that the password you are trying to set is not available in any of their collected breaches. Verifying whether the password is in any of these breaches happens without giving HIBP access to your password!
