KeePass Password Safe is a free and open-source password manager. I already wrotte a blog post 7 years ago about how to sync keepass to Google Drive. The howto is out of date, so I propose a new one :). This time, We’ll use the plugin KeePassSyncForDrive

1 / Plugin

Download the plugin : KeePassSyncForDrive

Copy & Paste the plugin file in the Keepass Folder :

Start KeePass, and go to Tools, to see the plugin

2 / Create a Google API Key

• Go to the Google Developers Console in your Google Account:
  https://console.developers.google.com/start
• Select “Enable Google APIs for use in your apps“.
• Choose a Project name like e.g.: “KeePass-Sync”.

• In API & Services, click on “Library”

and activate the Google Drive API

• Then go to “OAuth consent Scren“, create the app registration :
  • App Name : KeePass Sync Drive (for example)
  • user support mail : your mail

• Next page, “Scopes“, add the following :

• Next Page, In the test user, add your gmail account,
• Then, save the configuration.

• Now you can go to the “Credentials” Page
• Click on “Create Credentials“, and select “OAuth Client ID“
  • Application type : Desktop App
  • Name : What you want
• Then, click on create

Keep your client ID & your Client Secret for the next step

3 / KeePass configuration

• Create a new entry in KeePass with :
  • title : accounts.google.com
  • url : accounts.google.com

• Now, navigate to “Tools“, “KeePass Sync for Google Drive” & Configure

• Enter the following parameters :
  • KeePass Entry Title : accounts.google.com
  • Target Sync Folder : The folder of your choice, can be empty
  • Enable Legacy OAuth 2.0 Credentials : Yes
  • Client ID : Your Client ID
  • Client Secret : Your Client Secret

• You can click on Upload to drive
• A pop up asking your account will appear,
• Allow Keepass to access your drive

You now have your KeePass database on Google Drive, and you can sync it :)
