Frequently Asked Questions

What makes a strong password?▾

A strong password is: long (minimum 16 characters), random (not a word or phrase you chose), and unique to each account. Length matters more than complexity - a 20-character random lowercase string is stronger than an 8-character string with special characters. The most secure approach is using a password manager to generate and store a different random password for every account, so you only need to remember one master password.

What is a passphrase and is it more secure than a random password?▾

A passphrase is a random sequence of common words (correct-horse-battery-staple) - easier to remember than random characters while providing comparable or better security through length. A 4-word passphrase from a large wordlist has approximately 50 bits of entropy - adequate for most purposes. For accounts you need to type manually and remember (master password, device PIN), a passphrase is preferable to a random character string.

Is it safe to use an online password generator?▾

Reputable browser-based password generators (like Bitwarden's online generator) generate passwords client-side using JavaScript - they are never sent to the server. Check the page source or use the browser's network tab to verify no request is made when generating passwords. For maximum security, use the built-in password generator in your password manager, or generate passwords locally using a desktop tool without internet connectivity.

What makes a password strong?▾

Length and randomness matter most. A strong password is long, at least 12 to 16 characters and ideally longer, and unpredictable, avoiding words, names, dates, and common patterns that attackers guess first. Mixing character types, uppercase, lowercase, numbers, and symbols, increases the possible combinations, but length contributes even more to strength than complexity. Crucially, each account should have a unique password, so that a breach of one does not compromise others. A random string from a generator, or a long passphrase of unrelated words, achieves this. The weakest passwords are short, based on personal information, or reused, which is exactly what generators and unique passwords prevent.

How do I remember randomly generated passwords?▾

You generally do not, and that is the point, you store them in a password manager instead. A manager keeps all your generated passwords in an encrypted vault and fills them in automatically, so you only need to remember one strong master password. This lets you use long, unique, random passwords everywhere without memorizing any of them, which is far more secure than relying on passwords simple enough to recall. If you must remember a particular password, such as the master one, a passphrase of several random words is strong yet more memorable than a random string. For everything else, let a password manager handle storage and entry.

Are password generators safe to use?▾

Reputable ones are, especially those that generate passwords locally in your browser without sending them anywhere. The best practice is to use a generator built into a trusted password manager or a well-known tool that clearly generates passwords on your device rather than on a server. Avoid obscure sites that might log generated passwords, and never use a password that was displayed on a page you do not trust. Generating a password and immediately storing it in your password manager, then using it only for one account, keeps it safe. The randomness of a good generator is far stronger than human-chosen passwords, so the main caution is simply choosing a trustworthy tool.
