📖 Description
1. Why Do You Need Professional Random Passwords?
In today's world of increasingly frequent cyber attacks, simple passwords (like 123456 or birthdays) are extremely easy to crack:
- Prevent Brute-Force Attacks: Long passwords containing uppercase and lowercase letters, numbers, and special symbols exponentially increase the number of possible combinations, rendering hackers' exhaustive attacks futile.
- Avoid Credential Stuffing Attacks: Using unique random passwords for each website ensures that even if one account is compromised, your core assets like online banking and email remain safe.
- Meet Security Requirements: Many banking or corporate systems require passwords to include various character types and meet specific lengths, which is extremely tedious to create manually.
- Eliminate Memory Burden: When used with password management software (like 1Password or browser built-in saving), random passwords allow you to completely forget the hassle of "forgetting passwords."
