is possible to connect in mikrotik via console without password ???

Thx

When I read your question, it really sounds to me like "can I unlock my door without a key?" So think of what are the ways to get through that door without a key? The same applies to router. Reset.

Unfortunately you are pretty much screwed. You could try this. I have never tried it.
