Logging in is email, password, captcha. The session lasts a day before it asks again. The only thing worth being paranoid about is the URL; phishing clones of casino domains are common and the difference is often a single hyphen.
Most account locks I saw were dull: three wrong passwords, a new country, sometimes a VPN. In my test the password reset email solved it faster than arguing with support.
If you travel, send support a quick note before you go. I learned that one the hard way after a trip to Germany got my account frozen on a Saturday night, when nobody was around to unfreeze it until Sunday afternoon.
Turn on 2FA the first time you sit down with the account. Google Authenticator works fine. If you reuse the same password as your email, fix that first; a casino account with money sitting in it is a worthwhile target.
