"Safe" passwords are long, random, generated by an app and hated by users. The reason they are hated is because they are difficult to type and remember and should be unique to every different account. The challenge is that weak passwords leave your business vulnerable to hackers. Short passwords can be cracked using automated software developed for this purpose - by trying every combination until they succeed.
