Re: Thanks. the logfile follows. I opened the connection and then unplugged the network for 20 seconds.

I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

Thanks. the logfile follows. I opened the connection and then unplugged the network for 20 seconds.

You can see that after I plug the network back in, it asks me for the password. If I only unplug the network for 3 seconds then it does remember the password. It only loses the password AFTER the first re-connect attempt fails. WinSCP 5.17.10.11087

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem).

In WinSCP 5.17.10 the REMEMBER PASSWORD FOR DURATION OF SESSION feature fails whenever AUTOMATICALLY RECONNECT SESSION IF IT BREAKS WHILE IDLE times out. This happens when the remote computer reboots because that generally exceeds the initial timeout and short time-outs are desired.

After the time out, WinSCP does indeed retry but these subsequent attempts do not remember the password. Something is causing the password to drop out as soon as the first attempt fails. Compare to how KiTTY implements the Remember Password feature for the local session, where the password does not get lost after any timeout. KiTTY only loses the password if you exit the program.
martin

OK.
jsherk

Ok..

Normal login requires that I do the following:
-Double-click the desired stored session.
-Enter my password.
This is a very quick and easy login! But the problem is that it does not remember my password if I am disconnected and it will also require me to re-enter my password if I try to execute a command that requires SCP.

Login via the EDIT button requires:
-Single click the desired stored session.
-Move mouse over to Edit button and click Edit button.
-Move mouse over the Password field and click to focus on Password field.
-Enter my Password.
This method solves the problem mentioned above, but it requires a lot more mouse movement and clicks for the initial login.

So I guess I need to change my request back to my original request again ...
When I double-click my stored session and it immediately asks for my password, I would like to have an option that allows this method of login to remember my password, just like clicking the Edit button method does.

See screen shot of idea here, where it says "Remember Password for entire session":
<invalid hyperlink removed by admin>

Let me know if I am making sense!

Thanks

I do not understand. Please try to explain it again.
jsherk

Ah yes... you are right! I had (wrongly) assumed that entering your password on the Edit screen would save it permanently!

My only request now, is an option so that when you click Edit that it defaults in the Password field and not the Host Name field.

Thanks

That's exactly what it would do. Give it a try.
glauber

Filezilla does this (saves passwords in memory until the application is terminated). I agree it's a nice feature.
jsherk

I just thought of another good use case for this feature...

When I am logged in via SFTP and I want to run a command that requires SCP, it currently asks me to enter my password again... if password was stored, then it would just connect and run the command without asking me.

Thanks
jsherk

THanks for consideration.

Re: Remember password for current session only

I'll consider it. For now, you can use Edit button to load the session to Login dialog, enter password and click Login.
jsherk

Remember password for current session only

I do not store my passwords, so whenever I start up WinSCP and choose a server to connect with, it will always ask me for my password.

If the server disconnects me though, I have to re-enter my password to re-connect.

I would like the option of it remembering my password for the current seesion, until I close WinSCP. This way I can enter it once when I start up, but I won't have to enter it again it I get disconnected.

Thanks
