In the digital age, the security of your accounts directly depends on password strength. Statistics show that over 80% of data breaches occur due to weak or reused passwords.
A strong password must meet several criteria:
Length — at least 12 characters, ideally 16-20
Complexity — uppercase and lowercase letters, numbers, special characters
Uniqueness — not reused across different sites
Unpredictability — does not contain dictionary words, dates, or names
We recommend at least 16 characters for important accounts (banking, email) and at least 12 for others.
Enable all character types for maximum security:
| Character Type | Example | Number of Variants |
|---|---|---|
| Lowercase letters | a-z | 26 |
| Uppercase letters | A-Z | 26 |
| Digits | 0-9 | 10 |
| Special characters | !@#$%^&* | 32 |
Click the generate button, copy the password, and save it in a password manager.
Using the same password everywhere
Passwords that are too short (fewer than 8 characters)
Using personal information (date of birth, pet's name)
Simple patterns (qwerty, 12345, password)
Replacing letters with similar symbols (p@ssw0rd) — this has long been ineffective
Use a password manager for storage
Enable two-factor authentication wherever possible
Change passwords after data breaches
Use a unique password for each service
