Why do some websites limit password length?
Maximum lengths for passwords are a good thing to have. Long password denial of service is a thing that exists. Hashing algorithms that you use on the server side may have limits. More importantly, a known maximum password length allows you to test all of your password fields.
Why are weak passwords bad?
Devising and remembering a complex password for every account and website is virtually impossible on your own. Yet using weak and simple passwords is a recipe for data breaches, account takeovers, and other forms of cyberattack.

4.2. Poor, weak passwords have the following characteristics: The password contains fewer than eight characters. The password is a word found in a dictionary (English or foreign). Names of family, pets, friends, coworkers, fantasy characters, etc.

Why You Should Never reuse passwords?

Why are my passwords for my website so weak?
When your website is protected not only by very similar passwords but also weak ones, your information has a higher risk of getting into the wrong hands. If users create similar passwords for your organization’s accounts and databases, it will make it easier for hackers to access even more information, in a process known as the domino effect.
What’s the point of making passwords harder to guess?
The point of the restrictions is to (try to) make the password harder to guess by an attacker. Truly, preventing some users from using some specific password values mathematically reduces the number of possible passwords; but, practically, this is more about forbidding the easy passwords that users would almost always choose if they had the choice.
Is it safe to change your password on your website?

However, many experts have revealed that passwords aren’t the most secure tools to protect your website. Frequently changing passwords can lead to weaker website protection.
