1st drone-connection problems

I just bought a used DJI standard drone and have never had one before. I’m hoping someone could help me out. I created a DJI account with password, but when I try to connect using the DJI Go app I put on my android phone it says incorrect password. I read that someone said not to put any special characters in it so I deleted any of those but it still won’t connect. I’m older and recently retired so I just wanted something to take some aerial shots of our property and see if I wanted to get a better one later, but now I’m wondering if I just wasted the money since it. Any help or suggestions would be GREATLY appreciated.
