Generate secure random passwords
The MailDrop password generator creates strong random passwords directly in your browser. Choose a length between 4 and 128 characters, pick which character sets to include (uppercase letters, lowercase letters, digits, and symbols), and generate up to 20 passwords at once. Every password is built with the cryptographically secure random number generator provided by your browser, so the output is unpredictable and suitable for protecting real accounts.
Weak or reused passwords remain one of the most common causes of account takeovers. A long random password is far harder to guess or brute-force than anything a person invents, and generating a fresh one for every site limits the damage a single leak can do. Because this tool runs entirely on your device, nothing you generate ever leaves your browser or touches our servers.
The generator is completely free and requires no registration. It pairs naturally with MailDrop temporary email: sign up for a low-stakes service with a disposable email address and a unique random password, and your primary inbox and credentials stay out of the picture entirely.
Use the slider or the number field to pick a length from 4 to 128 characters. For most accounts, 16 characters or more offers a comfortable security margin without being unwieldy.
Tick the boxes for uppercase letters, lowercase letters, digits, and symbols. Including more character types increases entropy, but you can drop symbols if a site rejects them. At least one set must be selected.
Set the count field to produce between 1 and 20 passwords in a single batch. Generating several at once is handy when you are setting up multiple accounts or want options to choose from.
Click Generate and your passwords appear instantly. Use the copy button beside any result to place it on your clipboard, then paste it into your password manager or signup form.
With this tool, yes. All generation happens locally in your browser using the Web Crypto API, and no password is ever transmitted over the network or seen by our servers. You can verify this yourself: the page keeps working even if you disconnect from the internet after it loads.
No. Passwords exist only on your screen and in your clipboard if you copy them. We keep no logs, databases, or analytics tied to generated values. Once you close or refresh the page, the results are gone, so save anything you need in a password manager first.
Sixteen characters with mixed character sets is a solid default for everyday accounts. For high-value accounts like email or banking, consider 20 or more. Length matters more than complexity tricks, and since a password manager remembers it for you, longer costs you nothing in practice.
The tool uses crypto.getRandomValues, the cryptographically secure random source built into modern browsers. Unlike simple math-based randomness, it draws from operating system entropy, which makes the output unpredictable even to someone who knows exactly how the generator works.
Absolutely. When registering for a site you do not fully trust, grab a disposable email address from MailDrop and pair it with a freshly generated password. If that service is ever breached, the leaked credentials reveal nothing about your real inbox or the passwords you use elsewhere.
