![]() You may have seen dd used to copy one disk to another, but in this case, it is used to generate one block of random characters with dev/urandom. The "meat" of the script is in the line beginning with do dd. I don't know all the details of how this works, but I have done a bit of research and experimentation. #!/usr/bin/env shįor ((n=0 n /dev/null | uuencode -m - | sed -ne 2p | cut -c-12 ![]() Full disclosure: I found most of this script posted somewhere and made a minor modification to it. My mind often seems to draw a blank when I have to create a new login, and this short Bash script fills that void. This is much more practical these days if you use a password manager, as it can be incredibly easy to log into sites with a secure password that has been encrypted and stored in your browser or smartphone.Periodically, I need to come up with new passwords, some of which need to be more secure than others. And since the threat of security breaches are so prevalent, brute force hacking software so readily available, and all that other technical malfeasance mumbo-jumbo, one must use a unique complex password for every website or service they register for to maintain peace of mind. Until we use biometric security for everything, passwords are the solution. Generating long secure passwords that would be impossible and impractical to type yourself, or remember, or store on a piece of paper, is much more practical and necessary these days. Print: Choose to print the password, or just quick select to copy and paste it into your password manager, text file, etc. Entering the same character once will increase odds of it being selected. There is no logical reason to do this if a website is designed correctly, but they do.Ĭustom option and enter a specific custom set of characters and the password generator will select from them randomly. Sometimes a website prevents you from using special characters when saving a password, so you can exclude them by deselecting that option. Know what letters I wrote? Neither do I, that's why some people use this option, although it weakens the password.Ĭhoose which characters to include: Upper case, lower case, numbers, special characters. Plus they usually never tell you the upper limit, so you will likely cause the registration form to explode, and then have to keep chopping your password in half until you find it.Ĭryptographically random: Rather than relying on what is called basic "pseudo-random" number generation, this app uses modern algorithms to generate what are considered cryptographically strong randomization of the password for a more secure result.Įxclude ambiguous letters and numbers and symbols: for example, lower case "l"s, "1"s, upper case "I"s, any kind of "o", "O" or "0". Long: Generate long passwords (up to 50,000 characters)! Keep in mind, most websites arbitrarily restrict you to a maximum of 20, 30, or 100 characters because of a misunderstood fear of old fashioned coding realities, or laziness, or both. Hexadecimal: Quickly generate a password using only hexadecimal characters with this option. Wait, pavilion? It's happening.Īlphanumeric: Quickly generate a random alphanumeric password by selecting this option. Highly unlikely a dictionary word will show up in a single output, but, statistically speaking when you consider the probabilities, you are nearly guaranteed to see every dictionary word a gazillion times if you run the generator a pavilion times. Pronounceable: Generate a somewhat pronounceable random password. ![]() Multiple:You can also generate multple passwords at a time (up to 1000), if you feel like giving everyone at your organization a new password at the same time, or you're bored and want to test your browser's ability to load that much text. ![]() Just use this and ignore the other zillion options! Really, save the password to your browser or another password manager. These are some of the features of this online password generator:įast Secure: The fastest most secure way to generate a secure random password, it will include all keyboard letters, numbers and special characters by default. This app is only accessible via HTTPS secure online protocols meaning your data is encrypted in the same way your bank might encrypt their online traffic. The more types of characters you allow and the longer the password, the more secure the randomly generated password will be. Choose the types of characters allowed in the password and the length of the password (up to 50,000 characters) to generate as strong of a password as you want. You can also produce cryptographically strong random passwords, unambiguous, pronounceable passwords. Generate strong, secure, long, random passwords with this online password generator. ![]()
