Frequently Asked Questions

  • How do I create a strong password?

    A strong password should be at least 12 characters long and contain a combination of lowercase letters, uppercase letters, numbers, and symbols. Use this tool to automatically generate secure passwords based on your chosen settings. The longer and more varied the password, the more secure it becomes.

  • What do the different character types mean?

    Lowercase are small letters (a-z), uppercase are capital letters (A-Z), numbers are 0-9, and symbols are special characters like !@#$%. By combining multiple character types, you increase the password complexity and make it harder to crack. You can choose which character types to include in your generated password.

  • Are the passwords safe to use?

    Yes, passwords are generated directly in your browser using cryptographically secure random generation. All calculations happen locally on your device and no information is sent to any server. This makes the tool safe for creating passwords even for sensitive systems.

  • Are the passwords stored anywhere?

    No, the tool does not store any passwords. All generation happens locally in your browser without any communication with external servers. When you close the page, the passwords disappear completely, so make sure to save them in a password manager before leaving the page.

  • How many passwords can I generate?

    You can generate up to 100 passwords at once by specifying the desired amount in the form. This is practical when you need to create many unique passwords at once, for example for multiple user accounts or systems. Each password is generated individually and is unique.

  • Why should I use different passwords?

    Reusing the same password across multiple services means that if one service is compromised, all your accounts could be at risk. By using unique passwords for each service, you limit the damage in case of a data breach. A password manager can help you keep track of all your unique passwords.

  • How long should my password be?

    Security experts recommend at least 12 characters, but 16 or more is even better. A 16-character password with all character types (lowercase, uppercase, numbers, and symbols) has over 10³⁰ possible combinations — it would take longer than the age of the universe to crack with brute force. Avoid common words and personal information.

  • What is a passphrase?

    A passphrase is a password made up of several random words separated by hyphens, for example "Cat-Table-Sun-Forest". Passphrases are easier to remember than random characters but can be equally secure, especially if they contain 4–5 words. The tool generates passphrases from a Swedish word list.

  • How do I share a password securely?

    Never send passwords via regular email or SMS. Use our secure one-time link that automatically deletes after the recipient reads the message. To share the link on printed material, convert it to a QR code.

  • Do you need test data for development?

    For complete test data with passwords, personal IDs and contact details, use our test data generator. Export to CSV, JSON or SQL.
