Password Management

I’ve unfortunately largely practiced poor personal password hygiene (professionally there are typically sanctioned tools to avoid this issue). While I’ve used passwords that are unlikely to be guessed, I’ve tended to reuse some number of passwords across sites which is certainly asking from trouble on the modern Internet. I’ve typically avoided password management built in to software such as browsers since that was of little help if using a one-off device. Many of these concerns could be addressed by using something which is cloud based (either a dedicated manager or by synching stores from other software) but I’ve been reluctant to commit to handing over that data.

Like virtually everyone else on the Internet, at least some of my credentials have been compromised in some breach or other and are now floating around on the Dark Web, leading to occasional spam emails and presumably attempts to apply those credentials to alternative sites, so not adopting a better practice at this point seems foolhardy.

I started looking around for something open source a while ago; at the time I was leaning towards a solution that derived passwords based on some combination of a salt and per-use parameters (and therefore the passwords would not be saved anywhere) but searching around for readily usable solutions led me to pass(1). The software as a whole is certainly aligned with my general preferences and so far it seems to be working very well. Though I need to invest a bit more in getting it to do everything that can streamline my authentication needs, it provides a clear path for me to stop my terrible past habits.

An additional practice I’ve picked up is to use distinct usernames and emails for each site, typically by appending some form of suffix to a base value (for emails appending +<something> to the username acts as an alias for many mail servers). This is likely to be slightly more secure in that the username is half of the login credentials and so not reusing usernames will prevent any script kiddie replaying of credentials and at least present a slightly higher hurdle for anything more active or sophisticated. Additionally as any credentials do get compromised I can more easily identify the source of the leak.
