Authorization and Security
To start working with the Veeam Backup for Microsoft Azure REST API, users must first authenticate themselves and get authorization to make requests. Veeam Backup for Microsoft Azure REST API authorization process is based on the OAuth 2.0 Authorization Framework and involves obtaining an access token and a refresh token.
- Access token is a string that represents authorization issued to the client and that must be used in all requests during the current logon session. Access token expires in 60 minutes.
- Refresh token is a string that represents authorization granted to the client and that can be used to obtain a new access token if the current access token expires or becomes lost. By default, refresh token expires in 14 days. If you want to change the expiration period to 15 minutes, set the short_lived_refresh_token parameter value to true.
For increased security, Veeam Backup for Microsoft Azure allows you to use multi-factor authentication (MFA) to verify user identity. It is recommended to enable MFA for Veeam Backup for Microsoft Azure users. For more information, see Multi-Factor Authentication or the Veeam Backup for Microsoft Azure User Guide, section Managing Backup Administrator Accounts.
