There is no requirement for username. What are you referring to?
The text field during sign up must have characters. A "key is required" red label is shown and the signup does not processed.
that's not a username. Its just a display name for your key so you know which one is it. You can literally write anything you want. Otherwise it's going to be hard to switch accounts and selecting the right one.
I wanted tobmake a burner account. I do not feel like I can provide enough entropy to the name so multiple accounts would be named too similar. Could you allow for a bypass of the display name like it was a year or so ago?
Is this to be used just one time? Because otherwise we will need to improve a lot of screens to make sure you can find which account is which in the app. We usually hide most of the key..
Temporary usage. Let's say for a a few days. No need to immediatly revamp the UI. Having 2-3 accounts is fine. The robot and background color is enough to differentiate a few accounts. Only change would be adding text saying that the display name is optional and allowing the user to continue
