If you fear of credential usage, use 2FA on the accounts you use to log in on third party applications. If asked for credentials, log in as requested, and after you clear security, 1: change the passwordws and 2: force log out other sessions. I wouldn't mention anything about that accounts are used for logging in somewhere because that will flag you as someone weird/nonstandard and might lead you to some questioning. It they ask you stuff and you get nervous, you will be looked more. So, just do what you're asked and everything will be fine. BTW: your worst enemy crossing borders is Jet Lag. Since you're traveling from west to the east I guess this won't be an issue to you; but get some rest before boarding the plane and if you do not understand/hear well something tell the officer politely.
