My friend is asking for my fake accounts password, honestly its just a fake account but somehow I dont trust her? Am I exaggerating too much?

She text me yesterday evening also called me, i didn't hear the call aftwr seeing her call i knew she wants something from me because she calls me only when she needs something then i went to look what she texted me, she was saying if i can give my fake accounts password to her for 2-3 days, i didn't want to reply too early maybe someone will help her in those hours about that, and i just replied after 5 or 6 hours later at like 2 to 3 am, and told her i dont know that accounts passwords, now she text again and told me to change the password and giving the next password to her? But there's a lot reason i dont trust her, What can I say as an excuse to not give it?
