Stop Reusing the Same Password Everywhere
Most people know they should use a different password for every account, and most people still don’t. Remembering fifty unique strings is unrealistic, so we fall back on a pet name plus a number and reuse it. The problem is that when one website leaks its database, attackers try the same email and password on banking, email, and shopping sites. A password generator removes the temptation. It creates a random password for you, and you let a password manager remember it.

Steps to Create a Strong Password
- Choose the length. For important accounts, go for 16 characters or more.
- Pick the character types: uppercase, lowercase, numbers, and symbols.
- Generate the password and copy it.
- Paste it into the account’s password field and save it in your password manager.
If a website rejects certain symbols, turn symbols off and add length instead.
Length Beats Cleverness
A password’s strength is often described in bits of entropy, which measures how many guesses an attacker would need on average. You can work it out yourself. A random character picked from the 94 printable keyboard characters adds about 6.5 bits. So 8 characters give roughly 52 bits, 12 give about 78, and 16 give about 105. Lowercase letters alone add only about 4.7 bits each, so a 12 letter lowercase password has around 56 bits.
The lesson is simple. Every extra character helps, and truly random characters help far more than a clever pattern. “P@ssw0rd1!” looks complicated, but attackers’ wordlists include exactly this kind of swap, so it is weak in practice.
Random Password or Passphrase?
A random string such as q7Vn#2Lr9xTe is excellent for anything a password manager fills in for you. It’s miserable to type by hand.
A passphrase is several unrelated words, like four or five common words picked at random. Using the well known Diceware list of 7,776 words, each random word adds about 12.9 bits, so five words give about 65 bits and six give about 77. Passphrases are easier to type and remember, which makes them a good choice for the one password you can’t store anywhere else, such as your password manager’s master password. The words must be chosen randomly. A famous quote or a line from a song is not random.
What Makes a Password Weak
- Personal details: Names, birthdays, phone numbers, and your city are easy to guess or find online.
- Keyboard patterns: “qwerty123” and “1qaz2wsx” appear on every common password list.
- Small tweaks: Changing “Summer2024” to “Summer2025” is a predictable pattern.
- Reuse: A strong password used on ten sites is only as safe as the weakest of those ten sites.
- Short length: Short passwords can be tested exhaustively by modern hardware.
Where to Keep Your Passwords
A random password you can’t remember needs a safe home. Reputable password managers such as Bitwarden and 1Password, or the built-in managers in Chrome, Safari, and Firefox, store them encrypted and fill them in for you. Protect the manager with one long passphrase. Avoid keeping passwords in a notes app with no protection, in a plain spreadsheet, or on a sticky note beside your monitor.
Passwords Are Only Part of Security
- Turn on two-factor authentication for email, banking, and social accounts. An authenticator app is generally safer than SMS codes.
- Check for breaches. The website Have I Been Pwned lets you see whether your email appeared in a known leak.
- Use passkeys where offered. Many major services now support them as a phishing resistant alternative to passwords.
- Secure your email first. Password reset links go there, so a stolen email account puts everything else at risk.
For Developers and Site Owners
If a secret key or token was exposed in a config file or an API response, replace it right away and don’t try to keep using it. You can inspect such files safely on your own device, or tidy sample data with the JSON Formatter after removing real secrets. To see whether your own website sends security headers such as Strict-Transport-Security, run it through the HTTP Header Checker. For more practical guides, visit our blog.
About the Passwords You Generate
Never paste a password you already use into any online tool, and don’t share generated passwords by email or chat. Use the generator to create a new one, copy it straight into your password manager, and keep it private.

Frequently Asked Questions
How long should a password be in 2026?
Sixteen or more random characters is a sensible target for important accounts. Current NIST guidance also favors length over complicated rules and discourages forced password changes without a reason.
Are symbols required for a strong password?
No. They add variety, but length matters more. A long random password without symbols can beat a short one with them.
Is a passphrase safer than a random password?
Equal bits of entropy are equally strong. A random five or six word passphrase is easier to remember, while a random character string is more compact. Both beat a reused password by a wide margin.
Should I change my passwords every few months?
Not on a fixed schedule if they are strong and unique. Change one immediately if the site reports a breach or you suspect someone else has it.
Is it safe to use an online password generator?
It is safer when the password is created in your browser and never sent anywhere, and when you use it only for new passwords. If you have doubts, a password manager’s built-in generator is a solid alternative.
