Use a password manager that allows you to create and save your passwords in a safe way. Here are a few : Dashlane, 1Password or LastPass to create and storage your passwords

Your password must be at least a 8-characters one. Also, use capitals in the middle of words, and lowercases, use word plays or rare words, modify their spelling  and add symbols and numbers. Feel free to use a complete sentence as a password (example: SafePW4You).

Choose a different password for each website and account you have. This limits the impact of a breach on any of the services you use.

Never share your password with anyone. Once shared, they could be shared again with other parties or kept after you left the company.
