So I was trying to log into aim Phoenix whit my Phoenix username and password but I didn’t work ? What do I use to log into Phoenix AIM I’m s confused 
Yeah, I would advise against any of the “Phoenix” projects. I went to its website, and saw numerous things that were flags so red, they were crimson. I would look into Escargot/NINA instead.
Phoenix Proyect is very abandoned at this point, i recommend you use AIM of escargot.
