[quote="slawomir.pryczek"]Hi, i have an issue with winscp, after version 5.5.2 i can no longer use stored passwords.

The password is stored in UI, but it does request the password to be entered on login anyway, sending you both log files so you can compare new version 5.7.6 vs 5.5.2. I attached log from version 5.8 but 5.7.6 works the same. Thanks.

Re: WinScp 5.7.6 can't use saved passwords

2016-01-18

It was a bug between 5.5 and 5.5.4 that stored password was incorrectly used as a passphrase for a private key file:
https://winscp.net/tracker/1176

To provide a passphrase, use -passphrase switch of open command or save the private key unencrypted.
See https://winscp.net/eng/docs/faq_passphrase
