So I don't know why I am always being logged out that way but then, I am sharing this experience to let some others know that there is a high intensive of threats in holding your portfolio on the exchanges and also, note that while you are asleep. Scammers are awake troubleshooting on how to gain access to your wallet just to steal your coins.
This days I also discovered the issues like yours when i try to check my assets on my exchange my was account was also log out, and I try to login in back they where telling me that incorrect password till I reset new password before I can able to get my logged in back. But what I observed there is that they try to secure my account for me that’s why; May someone was try trying to get access to my assets.
Honestly scammer’s are very tough this days to get access to people wallet at midnight when the owners are sleeping, but the scammers are struggling on how to identify peoples login details, and that’s is very important for each an everyone to create a strong password to their wallet.
