From yesterdays thread hope it help..
OP then asked?:

Yup! First word: "mjotukj"

Prove you're in by posting the second word.

If you look at the numbers of the image and provided you could figure out an RSA code with them:
P = 509 (image height)
Q = 503 (image width)
--> N = P*Q = 256027
--> r = (P-1)*(Q-1) = 255016
All this leads to a potential encryption key of:
e = 3301 (!)
and decipher key of
d = 18541
