Might be a dumb question but can I use the same username and sign up for other instances? I have tried two different instances and it lets me make a account but then says my login info is wrong and I can't sign in.
I tried it on lemmy.world and lemmy.nsfw and both times it said I had the wrong log on but this was a few weeks ago so I'll give it another try. I even tried changing my password several times and nothing.
