    How to generate a strong password

    Use enough length

    Start with 16 characters for everyday accounts. Increase the length for email, finance, admin panels, and any account that can reset other logins.

    Keep the full character mix on

    Uppercase, lowercase, numbers, and symbols make the search space wider. Turn symbols off only when a website rejects them.

    Save it in a password manager

    A strong random password is not meant to be memorized. Copy it once, store it with the matching account, and avoid reusing it anywhere else.

    What makes a password strong?

    Length

    Longer passwords give attackers more combinations to try. Length is usually the easiest way to improve strength.

    Randomness

    Random output avoids names, dates, keyboard patterns, and reused words that attackers commonly test first.

    Uniqueness

    Every important account should have its own password. Reuse turns one breached site into a risk for other logins.

    Strong password settings that work well

    16 characters for most accounts

    This is a practical default for everyday sites when a password manager stores the result.

    20+ characters for critical access

    Email, banking, hosting, cloud, and admin accounts deserve longer generated passwords when allowed.

    All character types when accepted

    Keep letters, numbers, and symbols enabled unless the account form has a strict rule against them.

    Replace weak or reused passwords first

    Start with accounts that share an old password, then move to high-value logins.

    Strong password generator FAQ

    What makes a password strong?

    A strong password is long, unique, and hard to guess. Random passwords with uppercase letters, lowercase letters, numbers, and symbols give attackers a much larger search space.

    How long should a strong password be?

    Sixteen characters is a practical default for many accounts. Use more characters for email, banking, admin panels, and other high-value accounts when the site supports them.

    Should I include symbols?

    Yes, when the site allows them. Symbols increase the character pool. If a site rejects symbols, use a longer password with letters and numbers instead.

    Is a strong generated password safe to copy?

    Copying is normally part of the workflow. Paste the password directly into the account form or your password manager, then avoid sharing it through chat, email, or tickets.

    Are generated passwords sent to a server?

    No. PwdSeed generates passwords in your browser and does not upload generated password text to a server. Optional history is stored only in your browser's local storage.
