You can double check the web site by hovering your mouse over the link before you click on it. Be careful because links can be renamed to hide the url...so hover before you click!
I've been asked to sign in a few times. I don't know why that happens as I have not clicked on a link. I never re sign in. I refresh the page and it's fine.
Remember NEVER EVER give out your password. Steemit does not ask for your Owner Key. Don't use your Owner Key. You don't need it.
Here's info about the keys
The POSTING KEY is used for posting and voting.
The ACTIVE KEY is used to make transfers and place orders in the internal market.
