Website Login Issues
If you are having troubles saving a new Login or using a saved Login, there are a few limitations and workarounds.
Adobe Flash
1Password is unable to save and restore logins for sites that use Adobe Flash. As far as we know, no browser password manager anywhere supports Flash-based sites as it is a proprietary solution and does not interface with the browser much at all. After working with a Flash consultant and reviewing the latest APIs provided by Adobe we found it is still not possible unless websites modify their code to allow it.
Most websites realize the problems with using Flash and provide a standard HTML login page as well. If you cannot find one, the only workaround is to save the username and password in 1Password and copy and paste it whenever you need to log into the site.
Login Fails
If you have a saved Login that is not working, it may need to be re-saved. This is required because 1Password stores a lot of information about the login form and the web site may have changed, or perhaps the Login was imported from another system that did not store all this information.
To fix this, try logging in manually without using 1Password (you may need to copy and paste the password from the main 1Password application). Assuming you are able to log in (i.e., the password is correct), log out and then log in again, but this time save a new 1Password Login before submitting the login form. Log out again and then see if you can log in using the newly created item.
JavaScript Interference
If after creating a new Login the site still does not work, it is possible that the web site is using some JavaScript “tricks” when the login is submitted. Sometimes this code can interfere with the Autosubmit feature and cause it to fail.
To see if this is the cause, try disabling Autosubmit (deselect the Autosubmit checkbox on the 1Password toolbar menu) and logging in again using 1Password. If Autosubmit was indeed the cause, you can re-enable Autosubmit and disable it just for this item by editing it in the main 1Password application and changing its Autosubmit setting to Never.
