You can find a password checking utility on haveibeenpwned.com (the tool doesn’t send your password to the server, but only the first 5 characters of the hashed password, which is very safe). There are CLI tools on GitHub you can use to bulk test passwords. They also provide a downloadable list of hashes.

Alternatively, check if your password manager has a built-in tool for checking for passwords in known databases.
