    How to generate a strong password in 3 steps

    1. 1Choose length: Use the slider to set length between 8 and 64 characters. The NCSC and Cyber Essentials recommend a minimum of 12 characters - we suggest 16+ for admin, email and banking logins.
    2. 2Pick character types: Tick uppercase, lowercase, numbers and symbols. Including all four sets gives the highest entropy and protects against brute-force attacks.
    3. 3Generate and copy: Click Generate New Password, then the copy icon. Paste into your password manager (we recommend Bitwarden, 1Password, or the Microsoft Authenticator built into Edge).

    Why strong passwords matter for UK businesses

    Compromised passwords remain the single largest attack vector for UK SMEs. According to the UK Government Cyber Security Breaches Survey 2024, 50% of businesses reported a cyber attack in the last 12 months, and weak or reused passwords were the entry point in the majority of credential-based incidents. Once an attacker holds one valid password, credential-stuffing tools test it against hundreds of other services within minutes.

    A 16-character password mixing uppercase, lowercase, numbers and symbols has roughly 9516 possible combinations - approximately 4.4 × 1031. Even at one trillion guesses per second, brute-forcing such a password takes longer than the age of the universe. By contrast, an 8-character lowercase-only password can be cracked in under a second by a modern GPU rig.

    Strong passwords are also a Cyber Essentials requirement. To achieve certification, UK businesses must enforce a minimum password length, implement multi-factor authentication, and prevent the use of breached or trivially-guessable passwords.

    Frequently asked questions

    How does this free password generator work?▼

    Our password generator runs entirely in your browser using the cryptographically secure window.crypto.getRandomValues() API. No password ever leaves your device, is sent over the network, or stored on any server. It is 100% free, with no sign-up required.

    How long should a strong password be in 2026?▼

    For a random password stored in a password manager, aim for at least 16 characters where the service allows it. Account requirements and authentication policies differ, so there is no single minimum that applies to every service. For passwords you must remember, the NCSC recommends three random words. Use multi-factor authentication as well.

    Is it safe to use an online password generator?▼

    It is safe if the tool runs locally in your browser and does not transmit the password. This tool generates the password entirely client-side - you can verify by opening your browser's network tab while generating. Avoid any password generator that requires you to sign in or sends output to a server.

    What characters should I include in a strong password?▼

    Choose the character types your account accepts. Length, randomness and uniqueness matter; adding a symbol does not make a short or predictable password strong. When symbols are not supported, use a longer random alphanumeric password. The selected options form the available character pool, not a guarantee of at least one character from each type.

    Should I use the same password for multiple accounts?▼

    Never. Credential-stuffing attacks reuse leaked passwords from one breach to access dozens of other accounts. Use a unique password for every login, and store them in a reputable password manager such as Bitwarden, 1Password or the password manager built into Microsoft 365 Edge.

    How often should I change my password?▼

    Modern NCSC guidance is to change passwords only when you suspect compromise, not on a forced schedule. Forced regular changes lead to weaker, predictable passwords. Combine a long unique password with multi-factor authentication for the strongest protection.

    What is a passphrase and is it stronger than a random password?▼

    A passphrase combines randomly chosen words and can be easier to remember. Its strength depends on the word list, word count and how the words are chosen. Avoid famous examples, quotations and predictable phrases. This tool generates random characters, not word-based passphrases; a password manager can store them for you.
