KeePass Google Drive Sync Plugin Authorization Failed

Many of us use a password database to keep track of the hundreds of passwords we create for our online accounts, I use a password database called KeePass, it works by creating a local database which you could store on your computer or a USB drive which is encrypted without password and keyfile, for the sake of convenience there is a plugin enables you to sync your password database 2 your Google Drive account so you can load it remotely or install the KeePass app on your phone.

I have been using KeePass for years and it has served me really well, however recently I encountered an issue with the Google Sync Plugin which displayed the message "Authorization failed: access_denied"

Google Sync Plugin - Authorization failed: access_denied

I tried a range of things to rectify the problem such as updating the plug in and updating key pass however none of my attempts resolve the issue one of the key issues is that due to the native code using an Internet Explorer window for the Google login page and the fact that Google login page no longer works properly in Internet Explorer, I had quite the problem trying to login to my Google account and authorize the Google Sync Plugin.

Fortunately after scouring the web trying to find solutions I found a few Registry hacks that I could use to force the application to run the browser in compatibility mode and enable a setting called "Feature Browser Emulation" and thus I now have a simple 2 step process to resolve this issue.

Disable / Uninstall Internet Explorer

1. Open Control Panel and navigate to Programs and Features
2. In the left pane, click Add/Remove Windows Components
3. Find Internet Explorer and Uncheck it
   
4. Click OK and if necessary restart your computer.

Apply Registry Changes

The final step in resolving the issues with the KeePass Google Sync Plugin is making some changes to the registry to enable compatibility mode in the IE browser and enabling feature emulation.

1. Download my keepass.reg file, or alternatively you may also find the raw code of the reg file embedded below.
2. Right-click on the downloaded keepass.reg file and select Merge
3. Confirm you would like to merge the entries by clicking Yes
4. You should get a message confirming the keys were added successfully.

That should be all you need to do to get the Google Sync Plugin working again, if these steps don't resolve the issue I would suggest updating KeePass and trying again, I hope this helps.
