Please describe your issue in as much detail as possible:

When I check "Remember my password" box, Steam seem to remember the password and try to log me in the next times I open it.
But that step is always failed, it will show the text "Connect Steam account: ***** " then prompt me to manual enter password and Steam Guard code.
If I enter password and Steam Guard code, then it can successfully log me in.
If I refuse to fill in the password and turn steam off with "Remember my password" box still checked. It will continue to "Connect Steam account" the next times I open steam. Do this a few times, steam will prompt that there were too many failed attempt from this network and I must wait before I try to log in again.
All this only happens to my account. I had tried this with 1 other account that don't have Steam Guard and it didn't have the these problem.

Steps for reproducing this issue:

1. Enter login details, with the "Remember Me" box checked.
2. After logging in, exit steam.
3. Open steam.

Expected result:
Steam remembers my account info and logs me in automatically.
