When it comes to creating passwords, one of the most important criteria is complexity. Passwords that are easy to guess can be broken by hackers in a matter of seconds. Two passwords that often appear on top of “least secure password list” are 123456 and 123456.

Both of these passwords are identical in their composition and contain all numerical digits in an ascending order. This pattern makes it extremely easy to guess, so it should never be used for any purpose.

What differentiates the two passwords are their strength ratings. Password strength rating is calculated based on its complexity and other parameters such as length. 123456 has a strength rating of 0% which indicates that the password is extremely weak and vulnerable. On the other hand, 123456 has a rating of 50%. Although this is still considered a very weak password, it is more difficult to crack than the former one.

In conclusion, it is clear that both of these passwords should be avoided. It is essential to create strong, unique, and complex passwords and keep them in a secure place.
