Your password generator should not be collecting data about you. Here is why most tools fail at this basic requirement, and what to use instead.
Think about what you are doing when you use a password generator: creating the literal keys to your digital life. Your bank account, your email, your crypto wallets, your medical records — all protected by passwords.
Now think about what most online password generators do. They load Google Analytics. They set tracking cookies. They serve ads from networks that build profiles on you. Some send your generated password to their server before displaying it.
This is backwards. The tool you use to create security credentials should be the most private tool in your workflow, not the least.
The password must be generated entirely in your browser using JavaScript's crypto.getRandomValues() API. This is a cryptographically secure random number generator built into every modern browser. No server should ever see your password.
Open your browser's developer tools (F12, Network tab) and generate a password. If you see any network requests fire, the tool is sending data somewhere. A legitimate generator makes zero requests during password creation.
A password generator does not need to know who you are. There is no reason to create an account, verify an email, or log in. If a tool requires this, it is collecting data for purposes that have nothing to do with generating passwords.
Google Analytics, Facebook Pixel, Hotjar, Mixpanel — none of these belong on a privacy-focused tool. They track your behavior, your device fingerprint, and often your IP address. On a password generator, this creates an unnecessary link between your identity and your password creation activity.
Password strength is measured in entropy — essentially, how many guesses an attacker would need. Here is the math:
Generate a unique password for every account and store them in a password manager. The only password you need to memorize is your master password. Popular options include Bitwarden (free, open source), 1Password, and KeePass.
Even with a strong password, enable 2FA on every account that supports it. Use an authenticator app (not SMS — SIM swapping is a real threat). A hardware key like a Ledger device provides the strongest protection for your most critical accounts, especially cryptocurrency wallets.
When a site gets breached (and they do — regularly), attackers try those credentials on other services. If you reuse passwords, one breach compromises all your accounts. This is called credential stuffing, and it is the number one way accounts get hacked in practice.
Using all four types with a 16-character length gives you a pool of 94 possible characters per position. That is 94^16 possible combinations — a number so large it is effectively infinite for brute-force attacks.
If you are in crypto, password security is even more critical because transactions are irreversible. Your exchange account password and your wallet encryption password need to be maximum strength.
For securing crypto assets, use a hardware wallet. Ledger hardware wallets keep your private keys offline and require physical confirmation for transactions. Combine this with a strong, unique exchange password and you have solid protection.
Getting started with crypto? Coinbase is one of the most accessible platforms for beginners, and they provide solid security features including vault storage and address whitelisting.
