Question three. How Do I Migrate Using Oauth 2.Zero With Administrative Authentication?

Answer :

Follow the guidelines inside the Knowledge Base article KB005019 to installation the G Suite account to use OAuth 2.Zero. In order to offer us administrative authentication get right of entry to on your G Suite facts, add certain allowed scopes to the MigrationWiz assignment, as described within the article. Also, the object shows a way to allow API access, that's required for performing a Google Drive migration.

Question 4. What If I Want To Run A Migration On A G Suite Account Without Adding Oauth Credentials?

Answer :

If not the use of administrative authentication, then an OAuth 2.0 mission calls for user movements so that it will authorize MigrationWiz to access their facts. After filing a migration for mailbox(es), MigrationWiz will ship an e mail to each person mailbox so that it will ask for get right of entry to privileges. Once the user confirms get entry to privileges, their migration will start.

Note: 

Non-paid Google account migrations may even comply with the above OAuth 2.Zero challenge technique. It is vital emigrate those bills the usage of the person user name and passwords for each account.
Previously Google used "ClientLogin" for such migrations. This has been deprecated and replaced by using OAuth 2.Zero.
Here are some greater customary (non-unique to MigrationWiz) questions and solutions about OAuth and OAuth 2.Zero. These were protected right here to offer a few greater detail approximately how it works.

Question five. What Is Oauth?

Answer :

OAuth is an open preferred for authorization. OAuth offers customer programs a 'comfortable delegated get right of entry to' to server resources on behalf of a resource proprietor.

Question 6. How Does Oauth 2.0 Work?

Answer :

To get right of entry to protected data stored on Google services, use OAuth 2.Zero for authorization. Google APIs support OAuth 2.0 flows for one of a kind types of purchaser programs. In all of these flows, the purchaser utility requests an get right of entry to token this is associated with most effective the purchaser utility and the proprietor of the blanketed statistics being accessed. The get entry to token is also associated with a limited scope that defines the kind of statistics the client utility has access to (as an instance, "Manage your tasks"). An crucial intention for OAuth 2.0 is to offer relaxed and handy access to the included records, whilst minimizing the capacity impact if an get right of entry to token is stolen.

The normal work waft for OAuth 2.Zero requests:

When a person first attempts to apply functionality for your software that requires the person to be logged in to a Google Account or YouTube account, your utility initiates the OAuth 2.0 authorization process.
Your software directs the consumer to Google's authorization server. The link to that page specifies the scope of get entry to that your application is soliciting for for the user's account. The scope specifies the assets that your software can retrieve, insert, update, or delete while appearing as the authenticated user.
If the user concurs to authorize your application to get admission to the ones assets, Google returns a token on your utility. Depending on your utility's kind, it both validates the token or exchanges it for a distinct type of token.
For example, a server-side internet software exchanges the again token for an access token and a refresh token. The get right of entry to token lets the utility authorize requests on the consumer's behalf, and the refresh token shall we the application retrieve a new get right of entry to token whilst the unique get entry to token expires.

Question 30. How Do I Handle Tokens That Have Expired?

Answer :

The  complimentary strategies that builders may additionally take into account while dealing with expired tokens are as follows:

Track the creation of the OAuth get entry to token and use the refresh token at appropriate periods, based totally at the OAuth get entry to token advent time, on the way to generate a new OAuth get admission to token earlier than the expires_in parameter price for the modern OAuth access token has elapsed.
Capture the reaction with the HTTP Status code of 401 Unauthorized and invoke logic that retries the ideal Get Access Token method request, as follows:

Generate a brand new OAuth access token.
Use the brand new OAuth get admission to token to resubmit any formerly failed approach requests that failed because of an expired OAuth get right of entry to token.
In the future, AT&T may also alternate the default values of the expiration parameters for the OAuth access token and refresh token. So it is strongly recommended which you continually test the expires_in parameter price this is back with the response to the Get Access Token approach call.
