Mikä on Passwtaid Generaat→ri?
A Password Generator creates cryptographically random passwords based on your specifications. Choose length and character types to create passwords that are both strong and compliant with website requirements.
Milloin käyttää tätä laskuria
- Creating a new account — generate a unique, strong password for every new service.
- Replacing weak passwords — audit existing passwords and replace short or predictable ones.
- Setting up a password manager — generate your master password with maximum entropy.
- Generating API keys or tokens — create cryptographically random credentials.
- Securing shared accounts — generate a strong password for team-shared accounts.
- Meeting password requirements — customize character types to match website rules.
Vaiheet:
- Set the desired password length (8-128 characters).
- Select which character types to include: uppercase, lowercase, numbers, special characters.
- Click Generate to create a random password.
- Tarkista strength indicator and copy your password.
- Kopioi salasana leikepöydälle ja tallenna se salasanavalvontapalveluun.
Kaava
Password space = (Character pool size)^length
Entropy (bits) = length x log2(pool size)
- 72-bit+ = strong against offline attacks
- 128-bit+ = extremely secure (centuries to crack)
Käyttötapaukset
- Creating new account passwords
- Generating secure API keys and tokens
- Replacing weak reused passwords
- Luodaan ainutlaatuiset salasanat palvelua kohti
- Rakenna salasanavalvontapalvelu vahvoilla, monipuolisilla tunnisteilla
Keskeiset hyödyt
- Generate strong passwords instantly
- Customize character types and length
- See strength and entropy metrics
- Completely free and private
- Yhden klikkauksen kopiointi leikepöydälle hetittäistä käyttöä varten — ei manuaalista kirjoittamista tarvita.
- Täysin ilmainen ilman tiliä, mainoksia tai palvelinpohjaista käsittelyä.
Ammattilaisen vinkit
- Aim for at least 16 characters
- Use a password manager to store generated passwords
- Enable 2FA on all important accounts
- Generate a unique password for every account
- Älä koskaan käytä salasanoja uudelleen tileillä — tietovuoto yhdellä sivustolla paljastaa jokaisen tilin, joka käyttää samaa salasanaa.
Yleisiä vältettäviä virheitä
- Reusing passwords across accounts
- Using dictionary words or common substitutions
- Making passwords too short (< 12 chars)
- Storing passwords in plain text

Liittyvät käsitteet
- Password Entropy: A measure of password unpredictability in bits — higher entropy means a stronger password.
- Character Pool: The set of available characters used to generate a password — larger pools create stronger passwords.
- Brute voima Attack: An attack method that tries every possible combination until the correct password is found.
- Password Manager: Software that generates, stores, and autofills unique strong passwords for all your accounts.
- Two-Factor Authentication (2FA): An additional security layer requiring a second verification step beyond your password.
- Salasanalause: Satunnaisten sanojen sarjana salasanana — diceware- ja EFF-sanastot tarjoavat standardoituja sanatietokantoja vahvojen salasalauseiden luomiseen.
Esimerkki
A 16-character password using all 4 character types (pool of 95 chars) has 95^16 = 4.4x10^31 combinations. At 350 billion guesses/second, it would take approximately 4x10^12 vuotta to crack.
Tulosten tulkinta
Length matters more than complexity. A 20-character lowercase-only password (95 bits) is stronger than a 10-character mixed-type password (66 bits). Always maximize length first, then add character diversity. The entropy score tells you the real strength — aim for 72+ bits for general accounts and 100+ bits for critical accounts.
The strength meter provides a quick visual indicator, but the entropy number is more precise. Two passwords with the same character types but different lengths will have very different entropy scores. A password rated Strong with 80+ bits is sufficient for most accounts; Very Strong (100+ bits) is ideal for your password manager master password.
Käytä tätä generator in conjunction with a password manager. Generate unique passwords for every account, store them all in your manager, and never reuse passwords. The small effort of setting up a password manager pays enormous dividends in security.
