What you will find in the Generators category
The generators category contains five tools that create values on demand. The Password Generator makes random passwords of the length and character types you choose. The UUID v4 Generator produces version 4 identifiers that developers use as keys and reference numbers. The QR Code Generator turns a web address or a piece of text into a scannable code. The Lorem Ipsum Generator creates placeholder paragraphs for design work, and the Random Name Picker chooses one name at random from a list. All five run in your browser, so the values they create are produced on your device. Each page explains how the generator works, how to use the output safely and what its limits are.
Passwords and identifiers
Two of the generators produce security-related values. The password generator uses your browser's cryptographic random source, which is designed to be unpredictable, and the length you choose matters most: a 16 character random password has about 105 bits of randomness. Copy the password into a password manager, use a different one for every account and turn on two-step verification. The UUID generator creates version 4 identifiers with 122 random bits, so the chance of a duplicate is vanishingly small. These identifiers are good for database keys and file names, but they are not secrets and should not be used as passwords or reset tokens.
QR codes in practice
QR codes connect printed material to the web. A good code uses a short address, strong contrast and a clear margin, and it should be tested on more than one phone before printing. The generator creates the code in your browser, so the text you enter is not sent to a server. A code that links to a page on your own site can be updated by changing the destination, which is helpful for printed menus and posters. Be careful with codes for Wi-Fi, since they reveal the password to anyone who scans them, and be cautious when scanning unknown codes in public places, since they can lead to fake pages.
Placeholder text and fair draws
The Lorem Ipsum generator gives designers text with a natural rhythm without distracting readers with meaning, which is useful for testing layouts. It should always be replaced before a page goes live, since placeholder text on a published page looks unfinished and can be indexed by search engines. The random name picker is useful for classroom activities, small giveaways and deciding who goes first. It uses the standard random function of the browser, which is fair for informal choices but not suitable for regulated prize draws that require an audited method. Announce how you will draw, and keep the list and the result.
Choosing the right generator
Think about what you need the value for. If it protects an account, use the password generator and store the result in a manager. If it identifies a record in a database or a log, use the UUID generator. If you need a physical or on-screen link between a printed item and a web page, use the QR code generator. If you are building a layout and the copy is not ready, use Lorem Ipsum. If you need an impartial choice among a small group, use the random name picker. Matching the tool to the purpose avoids misuse, such as using a UUID as a password or a pseudo-random pick for a legal draw.
How the randomness works
Computers produce random values in two ways. A pseudo-random generator follows a formula that gives numbers that look random but can in principle be predicted if the starting point is known. A cryptographic random generator draws on unpredictable sources of the operating system and is designed to resist prediction. The password and UUID generators use the cryptographic kind, while the name picker uses the ordinary kind, which is fine for casual use. Knowing the difference helps you choose well: use cryptographic randomness whenever the value protects something, and ordinary randomness only for games, classroom choices and layouts.
Mistakes to avoid
Typical mistakes include reusing a generated password in several places, sending a password by chat or email, treating a UUID as a secret, printing a QR code without testing it, leaving Lorem Ipsum on a live page, and using a casual random picker for a draw with legal rules. Another is generating a password that the target site truncates or rejects because of its length or symbols, which leaves you with a different password from the one you stored. After you create a password, log in once to confirm that the site accepted it in full, and then save it.
Tips, privacy and limits
Every generator on this page runs in your browser, and what it creates is not sent to Dekuz or stored. Even so, you should treat generated passwords carefully, keep them out of screenshots and shared documents, and change any password that you may have exposed. The tools are free and need no account. If you need a feature that is missing, such as a different QR code size or a different kind of identifier, tell us on the contact page, and consider that we add tools according to how many people ask for them.
Frequently asked questions about the generators
Are the generated passwords stored or sent anywhere? No, they are created in your browser and are not sent to Dekuz. How long should a password be? At least 14 characters for ordinary accounts and 20 or more for a password manager. Can a UUID be guessed? Version 4 identifiers have 122 random bits, so guessing one is not practical, but they are identifiers and not secrets. Does the QR code expire? A static code never expires, but the page that it points to must stay online. Is the name picker fair? Each name has the same chance, but for regulated prize draws you should use an audited method.
A short glossary
Entropy measures how unpredictable a value is, in bits. A cryptographic random generator is designed so that its output cannot be predicted. A pseudo-random generator follows a formula. A password manager stores unique passwords securely. A UUID is a 128-bit identifier written as hexadecimal groups, and version 4 means it is random. A QR code is a two-dimensional barcode, and error correction lets it be read even if damaged. Lorem Ipsum is placeholder text derived from a work by Cicero. A raffle is a prize draw, and selection without replacement means that a chosen name is removed from the list.
Getting started: a suggested path
Try the Password Generator first and generate a few passwords of different lengths to see how they look, then store a real one in a password manager. Next open the UUID v4 Generator and create an identifier, checking that the third group starts with 4. Use the QR Code Generator to make a code for a web address, and scan it with two phones before you print it. If you are designing a page, generate a few paragraphs with the Lorem Ipsum Generator and try them in your layout. For a group activity, paste names into the Random Name Picker and draw one. Each tool page explains how to use the result safely.
Choosing sensible settings
The best settings depend on what you are making. For a password, length matters more than complexity, so use at least 14 characters for an ordinary account, 20 or more for important accounts and let a password manager remember the result. For a UUID, the random version 4 is the right choice when you need an identifier that is unique without a central register. For a QR code, keep the content short, because long text makes a denser code that is harder to scan, and test the printed code on more than one phone. For placeholder text, choose the number of paragraphs that matches the content you expect, and for a draw, prepare a clean list of names before you pick.
Responsible use of generated data
Generated values are only as good as the way you use them. A strong password that you reuse on several sites is still a weak habit, because one breach exposes every account. A UUID is an identifier, not a secret, so do not use it as a password or a key. A QR code can hide a web address, so people should scan only codes that they trust, and you should never print a code that points to a page you do not control. Placeholder text should be replaced before a page is published, and a random draw should follow the rules that apply to your group, school or country.
