If it is JUST your password you should be able to contact the company & access; check your email & work backwards.
BUT if you mean your CRYPTO Seed Phrase, String, Keys, etc., then I don't know about that one. But it's worth trying to figuire out if you can find your transactions on ETHERSCAN (or whatever) if you can trace the DATE, TIME & TRANSACTION (through your trading platform or app) & then SEE IF YOU CAN PROVE that was YOUR ENTRY!
I wish you luck! Let us know how it turns out (hopefully, a HAPPY ENDING!)
