Two-factor authentication using Two-Step Login (Duo) is required for access to the login nodes on IU research supercomputers, and for SCP and SFTP file transfers to those systems.
Therefore, you must either be able to log into the remote system with an established account username and password/passphrase, or have an administrator on the remote system add the public key to the ~/.ssh/authorized_keys file in your account. You need to be able to transfer your public key to the remote system.

This document includes instructions for generating a key pair with command-line SSH on a Linux or macOS computer, and with PuTTY on a Windows computer. The computer you use to connect to the remote server must have a version of SSH installed.If the remote system is using a different version of SSH (for example, Tectia SSH), the process outlined below may not be correct. The information in this document assumes the remote system uses OpenSSH. The remote system must have a version of SSH installed.Conceivably, you can share the public key with anyone without compromising the private key you store it on the remote system in a. You keep the private key a secret and store it on the computer you use to connect to the remote system. SSH public key authentication relies on asymmetric cryptographic algorithms that generate a pair of separate keys (a key pair), one "private" and the other "public". Using SSH public key authentication to connect to a remote system is a robust, more secure alternative to logging in with an account password or passphrase. Set up public key authentication using PuTTY on a Windows 11, Windows 10, or Windows 8.x computer.Set up public key authentication using SSH on a Linux or macOS computer.And for an amusing look at how most people actually do choose passwords, check out Your Top 20 Most Common Passwords and The science of password selection. What do you think? Is it easy to remember the other passwords generated here? Do you see some way to improve the algorithm? Is there any merit to this password selection strategy?Īs far as password management goes, I’ve personally found KeePass to be an excellent solution. Will it be just as easy to remember other four-word combinations? I think we’re more likely to remember “correct horse battery staple” for those reasons. But the strip itself is interesting, takes a lot of concentration to understand, and incorporates a visual aid. Sure, a lot of readers will probably have that phrase memorized for a while. The last panel claims that the reader has already memorized “correct horse battery staple”. It’s hard to be convinced about every detail in the strip, but it really had me thinking.

In any case, you can view the JavaScript source code here. This list doesn’t include “battery” or “staple”, so perhaps a better list is still possible. I scraped a list of 1949 words (close enough) from this site, which is based on the most frequent occurrences in newspapers. The xkcd strip suggests 11 “bits of entropy” per word, which can be achieved using a list of 211 = 2048 words.
For example, “decimalisation contrapuntal assizes diabolism” is not particularly easy to remember, I’d say. That’s important, because the more unusual words are used, the harder the password will be to remember. Other generators have popped up online, but unlike most of those, this generator only uses common English words. In case you missed the strip, here it is: (But if you’re just signing up for a kitten video forum, you’re probably safe.) Use at your own peril! I’m not responsible for anything that happens as a result of your password choice. It’s a novel idea, but xkcd stops short of actually recommending such passwords, and so will I.
