<a href="https://m.xkcd.com/2176/" rel="nofollow">https://m.xkcd.com/2176/</a><p>When I signed up to tax preparation services on hrblock.com, their security process forced me to choose a username that was not my email address, didn't contain my name, etc. So I was compelled to use a quite unique one at that.<p>Also when setting up online banking, my credit union offered me the choice of any username, so I chose one that was atypical and looked more like a generic "someone at this place" login than something connected to me.<p>These days it can get a little crazy when you have a singular email address, and it's your account sign-in practically everywhere on the Web. Or you have a persistent persona or pseudonym that more or less is replicated everywhere you go.<p>I'm thankful for centralized identity services. By now I'm taking advantage of "Sign in With Google" and Facebook logins for most services. That makes the password manager's space much more manageable!
