How do I generate an alphanumeric password without symbols?

The alphanumeric page starts with lowercase letters, uppercase letters and digits, with punctuation disabled. On any page you can switch the four sets independently, set 4 to 128 characters and exclude 0, O, 1, l, I and the pipe. When several sets are enabled, each output includes at least one character from each. Digits-only output can begin with zero; it is text, rather than a numeric calculation.

Can I generate an 8, 12, 16 or 32 character password?

Yes. Use the Length box for any whole length from 4 to 128. The quick choices are 8, 12, 16 and 24. A fixed length alone is not a strength promise: the alphabet, random generation, the receiving site and how the credential is stored all matter. A name or phrase you choose yourself is not the same random process.

Can I generate passwords in bulk or download a list?

Set Batch count from 1 to 100. Each password or passphrase is drawn independently using the settings on screen; repeats are possible. Copy batch puts one value per line on the clipboard, and Download TXT exports the same list with a final newline. Generated batches and the last five main values remain in this page only. A clipboard or downloaded file is a copy you choose to keep, so handle it like other credentials.

What does the entropy number mean?

For passwords it is the base-2 logarithm of the permitted output space, accounting for the rule that every enabled character set appears. Sixteen characters with all four sets is about 105 bits. For passphrases it describes the random word choices: each of the 2,048 words contributes 11 bits, and a random final digit adds log2(10), about 3.3 bits. Without a non-letter separator or capitalised boundaries, different word sequences can join to the same text, so that choice entropy is an upper bound for the final string. Strength labels are choice-space bands, not a measured cracking time or an audit of an existing password.

Are generated values saved or sent anywhere?

Generation runs in this browser. Values are not uploaded, put in analytics events or written into links. Only settings you explicitly change are remembered; opening a preset page does not overwrite unrelated remembered settings. The history and batch disappear on reload. Copy and TXT downloads are deliberate exports you control.

Alphanumeric Password Generator

Generate character passwords without punctuation. This page enables lowercase letters, uppercase letters and digits, disables symbols, and starts at 16 characters. Each password includes at least one character from every enabled set. Set any length from 4 to 128, exclude look-alikes if you need to type the result, or raise Batch count to generate a list. The outputs are plain ASCII letters and digits; they are not encoded words or account registrations.

The length box takes any number from 4 to 128, so an 8, a 12 or a 16 character rule is one keystroke away. Turning a set off drops it from the pool and lowers the entropy shown; excluding look-alikes removes 6 characters (0 O 1 l I |) for a password you have to read off a screen and type somewhere else.

Made here, kept here. Every character is drawn from crypto.getRandomValues on your own device by rejection sampling, so no position in the alphabet is favoured. The result is not sent anywhere, does not enter an analytics event and is never written into a link, and the only thing this page remembers between visits is your settings. It cannot know the rules a particular site enforces, so check its length limit and which symbols it accepts before you save one.

Accuracy. Passwords and passphrases come from the browser's own cryptographic randomness, made on your device and never sent anywhere. Entropy describes the random choices, not a cracking-time prediction. It cannot know a site's own password rules.
