Using birthdays, names, or simple numbers as passwords? Statistics show over 80% of data breaches involve weak or reused passwords. Your password could be cracked in seconds by brute force or credential stuffing attacks.
Suried Tools Password Generator uses cryptographically secure random numbers to generate truly random strong passwords with customizable length and character rules, plus a passphrase mode for memorable yet secure passwords.
01 Using the Password Generator
Open the Suried Tools Password Generator page and the tool automatically generates a default 16-character strong password. Copy it directly or customize settings and regenerate as needed.
Password generation uses the browser's crypto.getRandomValues() API — a cryptographic-grade secure random number generator ensuring genuine randomness and unpredictability.
Each click of the "Generate" button creates a brand-new random password — previously generated passwords are never recorded or stored.
02 Understanding Password Strength Indicators
Password strength is typically measured by "entropy" in bits. Higher entropy means the password is harder to crack. The tool displays the current password's entropy value and corresponding strength level in real time.
Generally: under 40 bits — weak, crackable in minutes; 40–60 bits — moderate, crackable in years; 60–80 bits — strong, decades to crack; over 80 bits — very strong, theoretically immune to brute force.
Beyond entropy, the tool also estimates the time required to brute-force the current password, helping you understand its strength more intuitively.
03 Customizing Password Rules
Different websites and platforms have different password requirements. Suried Tools lets you customize password length (8–128 characters) and character types: uppercase letters, lowercase letters, numbers, and special symbols.
You can choose to exclude easily confused characters (like 0/O, 1/l/I) — especially useful when passwords need manual entry. You can also exclude special characters not accepted by certain platforms.
- Password length: adjustable 8–128
- Uppercase letters A–Z
- Lowercase letters a–z
- Numbers 0–9
- Special symbols !@#$%...
- Exclude ambiguous characters option
04 Passphrase Mode
Beyond traditional random character passwords, the tool also supports Passphrase mode. It randomly selects 4–8 words from a curated wordlist, joined by separators, like "correct-horse-battery-staple".
Passphrases are easy to remember yet highly secure. A 4-word passphrase typically has 50+ bits of entropy, while a 6-word phrase reaches 77+ bits — already strong password territory.
You can choose different separators (hyphens, underscores, spaces, numbers) and whether to mix in capitalization variations or numbers for additional security.
Passphrases are perfect for master passwords that need manual entry (like password manager master passwords), balancing security and memorability.
FAQ
Are generated passwords saved or logged?
Absolutely not. Passwords are generated locally in your browser and never sent to any server. Passwords disappear when you close the page — the tool keeps no history whatsoever.
Are longer passwords always more secure?
Length is one of the most important factors, but not the only one. A 20-digit number-only password (like a repeated phone number) may be less secure than a 12-character mixed password. The key is length combined with character diversity. Recommend at least 12 mixed characters or a 4-word passphrase.
Why is it not recommended to create passwords manually?
Human brains have severe pattern biases when creating "random" content — we tend to use meaningful words, dates, and common substitutions (like replacing "a" with "@"). These patterns are cataloged in cracking dictionaries. Machine-generated truly random passwords don't have these weaknesses.
Should I choose a passphrase or a random password?
If the password is stored and auto-filled by a password manager, choose random character passwords (shorter but higher entropy per character). If you need to memorize and type it manually (like a master password), choose a passphrase (easier to remember).
Can I generate multiple passwords at once?
Yes. The tool supports batch generation mode — create multiple different passwords at once. Specify the quantity and all passwords use the same rules but are independently randomly generated.
