Infinite Passwords

Password Generator Without Symbols

Maximum strength within strict alphanumeric rules.

…

Random mode supports 4–128 characters.

Generate multiple

Shortcuts: R regenerate · C copy. Generated with crypto.getRandomValues() — never Math.random().

Some sites reject symbols outright. No problem — a 16-character alphanumeric password still carries ~95 bits of entropy. Symbols add flavor; length adds certainty.

Alphanumeric strength, honestly assessed

Letters+digits give 62 values per position. 16 positions ≈ 95 bits — stronger than most “with symbols” passwords at 12 characters.

For truly strict systems, push length to 20 — 119 bits with digits and letters alone.

When a Password Generator Without Symbols Is the Right Call

Plenty of systems flatly reject symbols: legacy enterprise portals, certain WiFi router firmware, old database front ends and rigid input validators that fail silently on special characters without telling you. In those situations a password generator without symbols — an alphanumeric password generator — is the correct tool for the job, not a compromise you grudgingly accept. Infinite Password Generator is free, runs 100% client-side, and nothing you generate is stored or transmitted anywhere at any point.

Dropping symbols shrinks the pool each position draws from to exactly 62 characters — 26 lowercase letters, 26 uppercase letters and 10 digits — so you lose a little entropy per character compared with the full 95-character set. The fix is straightforward and fully within your control: add length. Sliding the setting up a couple of notches restores the margin comfortably, and genuine randomness over mixed letters and digits still outclasses anything a person would invent by hand.

How to Use the Alphanumeric Password Generator Page

Set your desired length, then simply uncheck the symbols class and keep lowercase, uppercase and digits enabled — that is the whole configuration. Turn on exclude-ambiguous to remove 0, O, 1, l and I wherever manual transcription happens, such as router labels read over the phone. Generation remains instant and entirely local to your browser; copy the string, paste it into the field, and you are done — no account, no upload, no waiting.

Alphanumeric output fits anywhere characters are restricted or unreliable in practice: hotel kiosks and shared terminals where paste behaves unpredictably, WiFi setups with firmware that chokes on special characters, certain VPN clients, and strict enterprise signup forms ruled by unforgiving validators. For maximum compatibility at full strength, lean on the 20 character setting rather than shortening anything at all — length is cheap, and it is the one lever you always have at your disposal.

Beyond Symbols: Length, Uniqueness and Recovery Still Rule

Symbols add pool diversity, but length and genuine randomness dominate the security equation — a random nineteen-character alphanumeric decisively beats a short symbol-laden password decorated around a pet’s name and a meaningful birth year. The same rules apply either way you configure this particular tool: unique per account, held inside a manager you genuinely trust, never reused across services, and never typed from muscle memory where shoulders or phone cameras can casually observe the process happening.

Two-factor authentication covers the gap wherever a site’s restrictive rules force weaker secrets — the account no longer depends on password strength alone, which is the correct posture. Disciplined, prompt rotation after breach notifications covers the rest of the risk picture comprehensively. For other constrained fields — numeric PINs, easy-to-read passphrases and bulk resets — browse all generators; the full catalog exists precisely for systems with quirky and unforgiving input requirements.

The Real Cost of Dropping Symbols, in the Numbers

Symbols enlarge the pool from 62 to 95 characters per position — roughly 0.6 extra bits per character slot. Dropping them is not catastrophic; it is a small tax you repay with length. Twelve alphanumeric characters still deliver about 71 bits, comfortably past the practical floor, and fourteen alphanumeric push past 83. The genuine mistake is not unchecking the symbol class — the mistake is unchecking it while keeping the same short length you were using before, which converts a small, recoverable deficit into a real one overnight. Length is free entropy waiting on a slider, and unlike symbols it never trips a hidden validator, a picky form or a silent rejection. The math forgives you every single time, because length faithfully compensates for pool size.

The compensation rule is straightforward: add length. Every extra alphanumeric position multiplies the search space by 62, so two additional characters buy a factor of roughly 3,800 — far more than enough to recover the entire symbol deficit and then some. If the target accepts it, sixteen to twenty alphanumeric characters outclass a symbol-laden eight-character string by a wide and comfortable margin, and every site that balked at special characters will accept plain letters and digits without complaint or validator error. Alphanumeric strings also survive phone keyboards, kiosks and shared terminals far better than symbol soup, and they are dramatically easier to reproduce on a hotel business-center laptop in the wild. Length never argues back, never trips validation, and never gets rejected.

Use this page as the compatibility mode, not the downgrade mode. Weak-pool output is still unique, still genuinely random, and still immune to pattern guessing and dictionary attacks — it simply relies on length instead of diversity to do the heavy lifting. Keep it inside a manager, never reuse it across services, pair it with two-factor authentication on any account that matters, and if the field ever gains symbol support later, regenerate against the full pool at your leisure. Until then, random letters and digits outperform carefully chosen words and clever substitutions every time. The pool is honest about what it is: restricted, compensated and still comfortably beyond anything a person would invent unaided. Honest tools are the boring heroes of credential hygiene everywhere on the internet, and this is one of them.

Frequently asked questions

At 16+ characters, yes — ~95 bits of entropy. This is as strong as most symbol-included 12–14 character passwords.
Legacy input validation. Choose the longest length they accept — 20 alphanumeric characters is effectively uncrackable.
Always letters + digits — doubling the per-position space roughly.
Yes — nothing about alphanumeric output complicates clipboard use.
The right password is one that is random, unique to a single account, and long enough to resist brute force — full stop. It is not about looking complex; it is about being unpredictable to both humans and machines. If you can recall your own password by meaning, it is the wrong one.
A powerful password maximizes entropy: length first, then true randomness, then character-class diversity — and it must be unique per account. A 16-character random mixed string (~95 bits) is powerful; an 8-character one with clever symbols is not. Uniqueness is the multiplier that makes raw strength matter.
A password generator is a tool that creates random, hard-to-guess passwords using a cryptographically secure source of randomness. This tool creates them locally in your browser with the Web Crypto API (crypto.getRandomValues) — free, instant, and nothing ever leaves your device or is stored.
Three steps: 1) Open this site or any browser-based generator built on the Web Crypto API. 2) Set the length to at least 16 characters and enable upper, lower, numbers and symbols (exclude ambiguous characters only if you must type it by hand). 3) Click generate and copy the result into a password manager — never reuse it.
Yes — provided they are built on a cryptographically secure random number generator. This tool uses the browser’s Web Crypto API (crypto.getRandomValues), the same source used for TLS keys. That output is indistinguishable from true randomness, so guessing attacks perform no better than pure chance against it.
Anything short (under 12 characters), human-invented, reused across sites, derived from a leaked corpus (123456, qwerty, password), or padded with predictable patterns — a capital first letter plus a trailing exclamation mark does nothing against modern rule-based crackers.
A unique password is one used nowhere else — never before, never again, never a variant with a swapped symbol. Reuse is the single highest-impact failure mode in real-world breaches: one leak opens every account sharing the password. Generate a fresh one per account and let a password manager remember them.
The best password generator is free, client-side, cryptographically random and never stores what it makes. Every serious option meets that bar — and this site is one of them: no signup, no limits, Web Crypto API, zero network calls. The worst “free” generators are ones that phone your new password home.
There is no single perfect password — but a practically perfect one is long (16+ characters), fully random, unique to one account, stored in a password manager, and backed by two-factor authentication. Anything short, human-invented or reused fails at least one of those.
“123456”, without contest — it tops NordPass’s annual lists and multi-year breach datasets. It is so dominant that security guides open with it. If you have ever used it anywhere, rotate those accounts today.
Across leaked-credential analyses, the top of the table is consistently: 1) 123456, 2) 123456789, 3) 12345 — with “password” never far behind. Those three appear in more breaches than all complex passwords combined. Anything resembling them is pre-guessed on every attacker’s rig.
