Guys, how is password security different from its strength?

Question

Information Security

Is it distinguishable for a password?

Answer 1

Password security is the rights granted by the authorization system to this password.
Password strength is the difficulty in guessing this password.

Answer 2

It all depends on the authentication method.
Our bank card password consists mainly of 4 digits, or rather a pin code. And yet it is considered reliable.
If you think about it, then 4 digits is not a very strong password, but think about why it is so now all over the world).
