Where can I find my Account ID and Application Key?


You can find your Account ID and Application Key when you sign into your account and navigate to the Buckets page. On this page, click on the link that reads 'Show Account ID & Application Key".


You'll then see a window like the one below: 


IMPORTANT: When you click to Create Application Key, please save this key in a safe location that you can refer to later. Once you close this window, the current Application Key will not display again. You would need to create another Application Key if you lose the first one. The new key that you create will invalidate the old one. All the places where you have specified the Application Key will need to be updated, including tools like Cyberduck, Synology CloudSync, and the B2 command line tool.


You can now use your Account ID and Application key to use any of our integrated products or to authorize the B2 Command Line tool. 

If you need help with installing the Command Line tool, please refer to our documentation page here. Once the Command Line tool is installed, you will need to authorize your B2 account in order to make other B2 calls. First, you'll need to take note of your B2 Account ID and Application Key. 

Next, open up your Terminal/Command Prompt on your computer, type in 'b2 authorize_account', and Click Enter. Input your Account ID, click Enter, then your Application Key and click Enter.

Once completed, you will be able to use all of the command line calls for B2. You can run 'b2 help' for more information about each call in the Command line.

    Great tutorial, but how do you create a Bucket when there is no option under your account???

    I'm having the exact same problem. I created a bucket, and when I go back to the page, it just hangs. The page has been loading for about 10 minutes now, no content shows, and I can't create an application key. I even tried signing out and in again and a separate computer and different browsers.

    Any plans/roadmap to add multiple application keys?
    Ideally, multiple keys can be generated and given some kind of permissions, read only/write, only do things in x bucket.

    I am asking because these features are included with aws:s3.

    I agree with anabolic0omen - this feature would be invaluable, where you want to authorize say, b2 cli tool to only have access to one bucket.

    I'm still confused about the relationship between buckets and the application key. Is the application key unique to the account or to the bucket?

    If it is unique to the account, then do you use the same account id and application key when you create a new (2nd or 3rd or 4th.....) bucket?

    Really need to have multiple keys. I'm not going to use the same key in various web apps, that also has access to my backup bucket.
