I logged into AlphaBay, checked to make sure my security phrase was correct on the site(it was), and then deposited btc into my account. I pressed the home button and my account was logged out. When I try to log back in, it says "Authentication failed. Please verify your username or password." Thanks for any help
Hello, this sounds like a phishing case. There is no way to change the password of an account without knowing the original password. Since passwords are one-way hashed and never transmitted in clear, the attacker knows your cleartext password. It can be phishing, keylogging, or anything else.
If the account still has a PGP key and the attacker did not remove it, you can send a m3ssage to alpha02 on the marketplace using a signed message. If the attacker removed the key, or if the account had no key, you will need to make a new account. We urge users to use 2FA to avoid this kind of problems.
