Hi Ond, I believe you can use Discord to get in contact more with people to help you with these questions, but yes, you can always trust SteemConnect, and it seems that for now Partiko is winning in the most used app for steemit (I haven't looked at user numbers to compare, but most, including myself use Partiko.)

I have this problem before that you say about the words deleting but not online, nor on an app, sometimes just on Microsoft word etc, it must be something that we do.. still confuses me to this day when that used to happen regularly and it was very frustrating.

In regards to passwords, we have an owner key which doesn't have to ever be entered into a website to log in, which reduces the chances of someone being able to steal it. We can use out active key to log in with instead and to post with, although I just use my main key but have it saved with my username on Brave Browser so I'm also not entering it in every time.. Hope this helps..Like I say many Steemians are on Discord app
