Creating strong passwords remains one of the most effective ways to protect your online accounts. In 2026, guidance from organizations such as the National Institute of Standards and Technology (NIST) has shifted away from rigid complexity rules toward longer, more usable passwords and passphrases.
Why length matters more than complexity
Older advice focused heavily on mixing uppercase letters, lowercase letters, numbers, and symbols. Current recommendations emphasize length as the primary factor in resistance to guessing and cracking attacks. A longer password or passphrase is significantly harder for automated tools to break, even if it uses only common words or letters.
NIST guidance (SP 800-63B) recommends:
- At least 15 characters when a password is the only authentication factor.
- A minimum of 8 characters when used together with multi-factor authentication (MFA).
- Support for passwords up to at least 64 characters.
- Avoiding forced periodic password changes (change only if compromise is suspected).
- Allowing pasting and password-manager integration.
Practical steps to create a strong password
- Aim for 16 characters or longer whenever the service allows it.
- Prefer a random string or a passphrase of 4–7 unrelated words.
- Make every password unique — never reuse across email, banking, shopping, or social accounts.
- Avoid personal information, common patterns, keyboard walks, or dictionary words used alone.
- Use a cryptographically secure generator instead of inventing passwords yourself.
Passwords vs passphrases
A random password (for example a mix of letters, numbers, and symbols) offers high entropy but can be hard to type or remember. A passphrase such as four or five random words joined by hyphens or spaces can provide comparable strength while being easier for humans to recall. Both approaches work well when generated randomly and kept unique.
How a client-side password generator helps
Tools that generate passwords entirely in the browser (using the Web Crypto API) avoid sending any data to a server. This means the password never leaves your device during creation. Features such as adjustable length, character-set toggles, ambiguous-character exclusion, batch generation, and a local encrypted vault make everyday use practical without requiring an account.

Generate a Strong PasswordAdditional best practices
- Enable multi-factor authentication or passkeys wherever available.
- Protect your email account first — it is often the recovery path for other services.
- Use a reputable password manager for long-term storage across devices.
- Be cautious of phishing and unexpected password-reset messages.
- Screen new passwords against known breached lists when possible.
Strong, unique, long passwords combined with MFA dramatically reduce account takeover risk. Generate them with a privacy-focused tool and store them securely.
