Passwords are still the first line of defense for accounts, code, storage, and Wi-Fi. The SnipText Random Password Generator runs entirely in your browser so you can safely create strong passwords without sending data anywhere. It supports classic mixed-character strings, pronounceable options for easier typing, diceware-style passphrases for human memory, numeric PINs, and Wi-Fi keys.
What a password generator does
A secure generator builds random passwords from a chosen character pool and length, optionally following site rules. SnipText’s generator uses the Web Crypto API for entropy, allows batch generation, and never uploads data. You can copy or export to TXT and CSV for safe storage in a password manager.
Why strength and entropy matter
Entropy measures unpredictability. As a rule of thumb, more characters and a larger pool mean more entropy. Our meter estimates entropy in bits and shows a rough crack time for offline guessing. It is an estimate, but it gives clear direction: longer and more diverse beats shorter. Passphrases can be long and easy to remember. Classic strings are compact for fields with strict limits.
Types of passwords and when to use them
- Classic strong: Mixed lower, upper, digits, and optionally symbols. Good default for accounts and developer tokens. Try 16 to 24 characters.
- Pronounceable: Easier to type under pressure. Good for entry on mobile or TV screens. Slightly less entropy per character, so go a bit longer.
- Passphrase: Diceware-style multi-word phrases. Excellent memorability with high total entropy. Use 5 to 7 words and add a number or symbol if allowed.
- PIN: Numeric only. Use 6 to 8 digits at minimum. Avoid repeats and sequences; our tool can filter common PINs.
- Wi-Fi WPA2/WPA3: 12+ recommended, 20+ is better. Letters and digits are easier to share; you can avoid ambiguous characters for fewer mistakes.
Key features of SnipText’s generator
- Entropy and crack time meter: Quick feedback while you customize length and character sets.
- Ambiguity filter: Skip lookalikes like 0, O, o, l, I, 1 for fewer typing errors.
- Required characters and exclusions: Match picky site rules with ease. Add prefixes or suffixes when needed.
- Batch generation: Create many passwords at once, then copy or download TXT/CSV. Great for lab or classroom devices.
- Presets: Account default, Banking safe, Developer tokens, and Home Wi-Fi. One click to sensible settings.
- Client side only: Works offline in your browser. No uploads. No tracking of generated values.
Fast workflow and presets
- Open the Random Password Generator.
- Pick a type: classic, pronounceable, passphrase, PIN, or Wi-Fi.
- Select a preset or set length, character sets, and rules. Toggle ambiguity filter and required characters if needed.
- Generate one or a batch. Copy the first line or download TXT/CSV.
- Store safely in a password manager. For bulk records, export CSV and import into your manager or deployment scripts.
- Never reuse passwords: Use a manager to keep unique credentials per site.
- Increase length before symbols: Length adds entropy without hurting usability.
- Use MFA: Pair passwords with an authenticator app or hardware key where possible.
- Wi-Fi sharing: Generate an easy-to-type key. Print a QR in your home dashboard or share securely with guests.
- Compliance rules: Some portals require specific characters. Use required characters and prefix or suffix to comply without weakening overall randomness.
Best practices and common pitfalls
- Avoid common words, dates, names, and keyboard patterns.
- Do not paste passwords into chat or email. Copy directly into your manager or the sign-in form.
- Rotate credentials when staff change roles. Batch generation plus CSV export helps standardize this.
- For scripts and tokens, consider longer secrets stored in environment variables or your secret manager.

Open the Random Password Generator, select a preset, and create a batch of strong credentials. Save them to your manager and enable MFA. For Wi-Fi, pick an easy-to-type key and share it with guests using a QR or printed card.
FAQ
- Is the generator free
- Yes. It is free for normal use with no sign in. It runs locally in your browser.
- Do you upload or store generated passwords
- No. We do not send or store your passwords. We recommend saving in a trusted password manager.
- How many passwords can I make at once
- You can generate batches and export TXT or CSV. This is handy for classrooms, labs, and device fleets.
- Do I need symbols for a strong password
- Not always. Length matters more. A 20 character password without symbols is usually stronger than a short one with symbols.
- What passphrase length should I choose
- Aim for at least 5 words. Add a number or symbol if the site allows it, or increase word count.
