Create cryptographically strong random passwords with adjustable length, character sets, optional ambiguous-character exclusion, and an
entropy estimate. Random bytes come from crypto.getRandomValues — nothing is sent to DroidXP; generation and copy stay in your browser.
Multiple passwords appear as separate lines. Copy and paste into your password manager or site — clear the field when you are done on shared machines.
It builds random strings from the character sets you enable, using the browser’s cryptographically secure pseudorandom number generator (via crypto.getRandomValues), not
Math.random(). You can require at least one character from each selected set (then shuffled so position does not leak structure), exclude characters that are easy to misread in some fonts
(0, O, 1, l, I), and see a rough entropy estimate in bits based on alphabet size and length.
The tool shows ~bits × length where bits = log2(|alphabet|). That models ideal random choice from a uniform alphabet; real-world guessing depends on human behavior, leaked databases, and site policies. Treat the meter as a guide, not a guarantee. For high-value accounts, prefer a password manager with unique, long secrets per site.
Passwords are generated in your browser tab. DroidXP does not receive your output, your settings, or your clipboard — the same “local-only” model as our APK Analyzer and APK String Extractor: processing stays on your device.
No. Generation runs entirely in your browser. The page does not send your password or your settings to DroidXP servers for this tool.
No. Secrets are built from crypto.getRandomValues, which is the appropriate API for unpredictable bytes in modern browsers.
It removes characters that are often confused in sans-serif fonts: 0 vs O, 1 vs l vs I. That can reduce typing errors when someone must read the password aloud or type it by hand; it slightly shrinks the alphabet, which is reflected in the entropy estimate.
When enabled, the generator guarantees the password includes at least one character from every character class you selected (for example one uppercase, one digit, one symbol if all three are on). Remaining positions are filled randomly from the full allowed alphabet, then the whole string is shuffled so positions do not reveal which character was required for each slot.
Longer is generally better. Many organizations recommend at least 12–16 characters for web passwords, and more for high-value master passwords or passphrases. If a site caps length, use the maximum allowed with a strong random alphabet.
It is an estimate of log2(|alphabet|length) if each character were chosen uniformly at random from the combined alphabet. It does not include dictionary attacks, personal knowledge, or breached-password lists.
This tool can produce strong random strings, but master passwords and seed phrases carry extra risk. Use dedicated, audited workflows and follow your wallet or security product’s guidance; many prefer hardware-backed or offline generation for seeds.
Clipboard contents can be read by other apps on some systems, and may be logged by clipboard managers. Clear the field after use on shared machines, avoid pasting into untrusted apps, and prefer your password manager’s autofill where possible.
Yes — storing unique long passwords per site is one of the most effective practices. Use this generator to create new secrets, then save them in your manager rather than reusing one password everywhere.
You may have turned off all character sets, or enabled “at least one from each set” with a length smaller than the number of selected sets. Add length or enable fewer sets.
Yes — each line is generated with a fresh random selection from the same rules. They are independent for practical purposes within the browser’s CSPRNG.
