Password Generator
Create strong passwords from configurable character rules.
Generate random passwords in your browser with control over length, uppercase letters, lowercase letters, numbers, symbols, and ambiguous characters. The result updates when options change and includes a simple strength estimate.

Who this tool is for
Useful for creating unique passwords for new accounts, test accounts, Wi-Fi sharing, and temporary access.
Common mistakes
Before using Password Generator, check that the inputs and destination workflow match. These issues can make an output look useful while still being wrong for the real task.
- Do not reuse the same password across accounts.
- Do not paste generated passwords into untrusted chats or documents.
- Do not treat the strength label as a full security audit.
Limitations
Password Generator is a browser-based helper for quick preparation, cleanup, or checking. Keep the original material and review important output before using it in a formal workflow.
- The tool does not save or recover passwords.
- Password managers, two-factor authentication, and recovery settings are separate tasks.
- Local generation cannot protect a compromised device.
How to use
- Set the password length from 4 to 64 characters.
- Choose which character classes should be included.
- Turn on the ambiguous-character option when the password must be easy to read or type.
- Review the strength label, then copy the generated password.
Use cases
- Create a unique password for a new account.
- Generate temporary passwords for Wi-Fi, events, or test accounts.
- Make readable passwords that avoid characters people often confuse.

How to verify a Password Generator result before relying on it
This section covers Password Generator’s character-set logic, what “strength” is actually measuring, and what happens when every character class is unchecked.
Confirm the length slider and character composition
The page loads at length 16 with uppercase, lowercase, numbers, and symbols all checked. Every generated password is guaranteed to contain at least one character from each checked class before the remaining slots are filled randomly from the combined set and the whole string is shuffled — so at 16 characters with all four classes checked, you are certain to see at least one of each type, not just a statistical likelihood.
The strength meter is a simple length-and-variety score, not a real crack-time estimate
The strength label and colored bar are computed from length thresholds (12, 16, and 24 characters) plus how many character classes are checked — it does not model actual entropy, dictionary attacks, or known password-cracking speeds. A 24-character password using only numbers can score as “strong” on this meter despite far less real entropy than a shorter password mixing all four character classes, so treat the label as a rough nudge, not a security audit.
Unchecking every character class blocks generation entirely
Uncheck all four boxes (uppercase, lowercase, numbers, symbols) — leaving only “exclude ambiguous characters” as an option — and clicking Generate produces no password at all; an error asks you to select at least one class instead. Checking “exclude ambiguous characters” removes the letters O, 0, l, 1, and I from whichever classes are active, which shortens the effective character pool slightly and can matter at very short lengths.
Acceptance checklist
- At least one character class (uppercase, lowercase, numbers, or symbols) is checked — with none checked, Generate produces nothing.
- The strength label is treated as a rough length-and-variety hint, not a measured guess-time or entropy calculation.
- Length is set high enough (16+ recommended) rather than relying on “exclude ambiguous characters” or symbol variety alone for real security.
- A freshly generated password — not a modified or partially retyped one — is the one actually copied and used, since editing it by hand defeats the randomness guarantee.
Who is it for
- Useful for creating unique passwords for new accounts, test accounts, Wi-Fi sharing, and temporary access.

FAQ
- Is the password uploaded?
- No. Generation runs in the browser.
- Why exclude O0l1I?
- Those characters can be confused in some fonts or when spoken aloud.
- Is the password stored?
- No. Save it in a password manager you trust.
- Is longer always safer?
- Length helps, but account safety also depends on reuse, two-factor authentication, and device security.
- Can I use this for a company policy?
- Check the company’s length, character, storage, and rotation requirements first.
