That was the reason of our fail – ROT47. Do you know what’s that?

*ROT47 is a derivative of ROT13 which, in addition to scrambling the basic letters, treats numbers and common symbols. Instead of using the sequence A–Z as the alphabet, ROT47 uses a larger set of characters from the common character encoding known as ASCII. Specifically, the 7-bit printable characters, excluding space, from decimal 33 ‘!’ through 126 ‘~’, 94 in total, taken in the order of the numerical values of their ASCII codes, are rotated by 47 positions, without special consideration of case.

Ok, let’s find what we can decode using ROT47. Login __D92:=6?5C2__ and it’s password __4J36CDA=@:E`__ look suspicious so let’s try to decode it.
