I've been using RDM for almost 10 years now, starting with the free version and eventually moving to the Enterprise version. There is not a day that goes by that I do not use the tool. 

Use the built-in Password Generation tool.

1. You can store password policies as templates and just call the template to generate a bunch of different passwords that follow the policy and password security best practices.
2. Press the button, and it is stored in your credential store.
3. Copy it into the new password fields, and all of a sudden, you are using best practices on your passwords, effortlessly.

It actually takes more effort to do less than the best practices while using this tool!

Try it and you will be impressed.
