Is Using a Password Generator Safe? [with 13 Bonus Tips]


There are many password generators out there, and people rely on them daily for creating their passwords for various websites. However, many people wonder if these online password creators are secure. Are the passwords truly randomized? Is using a password generator safe?

Using a password generator is safe for general purposes. The most secure generators are open-source and run on the user’s device instead of within a browser. Adding some characters to a generated password will make it truly random. The strongest passwords combine length and larger character sets.

This article aims to explain what a password generator is and what it does. We will also go over whether password generators are safe and also how a password generator works in providing randomized sets of characters to use for your passwords. We will also provide you with some tips on the best ways to keep your online accounts and passwords safe and secure.

What is a Password Generator?

password generator is a piece of software that creates a randomized custom password for its users. This application helps users produce more robust and more secure passwords for whatever they need to create a password. It also helps them come up with a different random password for each site or service to provide the most security possible.

Some password generators are simple random sequence generators. This type of software produces a secure password containing upper and lower case letters and numbers. It will also include special characters such as slashes, asterisks, and braces.

Other types of password generators create more recognizable passwords as opposed to a completely random set of characters. Some tools produce actual words that appear in the dictionary. There are also generators with configurable settings to match password varying requirement criteria.

Password generators are beneficial for people who always need to come up with new passwords to protect access to sensitive programs and to manage a lot of different passwords at once.

There are also other tools available such as a password vault, a place where users can manage several passwords in a very secure location.

Several popular password generators and password managers exist and cater to people with different levels of skill or security requirements. Check out our Recommended Tech page for our current recommendations.

These password vaults store your passwords so that you can easily log in without the need to search or remember your passwords. They include a password generator function to help you create randomized, safe passwords for each of your different accounts.

Is a Password Generator Safe?

Password generators are generally safe for creating strong passwords for WiFi and many situations. If you need to create a single secure password or several passwords at a time, then a password generator is definitely worth using.

Password generators tend to create lengthy passwords. With this in mind, there are millions of possibilities of passwords that will be generated from one password generator before it begins to repeat itself.

For optimum safety when using a password generator, it’s good to mix up some of the characters and even add or remove some characters before using it. In addition to the generated random password, you also introduce your added randomization, creating an even safer password that is unique..

Are Password Generators Truly Random?

Throwing a pair of dice produces a genuinely random result – it’s impossible to predict the numbers that you’re going to get. However, in the computing world, a physical randomizer, such as a pair of dice, isn’t available.

Password generators and other sites that produce randomly generated content use something called a pseudo-random algorithm. This algorithm begins using a number, letter, or sequence known as a “seed.” The algorithm processes this seed and gets a new result with no traceable connection to the old one.

The new sequence then becomes the seed. The original seed will not come up again until every other combination has been produced.

For example, if a seed is a 32-bit integer, the algorithm would have to run through 4,294,967,295 other numbers before repeating the original seed.

A password generator, of course, doesn’t return only random numbers. It instead returns a string of characters using random numbers to create passwords from the available character sets. Since a computer can’t generate an entirely randomized set of characters, this is the “most random” way to create a mix of characters in technology.

Why Should You Change Your Password Regularly?

Security experts the world over suggest that online internet users should regularly change their passwords. It can be frustrating and overwhelming to come up with a new, strong, and secure password.
