When you start a new project using Atlas, a username and password are suggested. The username and password fields use a font with almost identical lowercase L and capital i.

My suggestion is to use a monospace font in those fields for disambiguation.

I use a password manager on my phone (as do, I imagine, many others), which means it’s very annoying to have to figure out if a character is an l or an I on the computer every time I have to copy down info for a new project.
