Gets and sets the method used to authenticate the user.
Syntax
object.AuthType [= type ]
Remarks
The AuthType property specifies the type of authentication
that should be used when the client connects to the mail server. The
following authentication methods are supported:
| Value |
Description |
| imapAuthLogin |
This authentication type will use the LOGIN method to
authenticate the client session. This encodes the username and
password in a specific format, but the credentials are not
encrypted. It should be used over a secure connection. The
server must support the Simple Authentication and Security Layer
(SASL) mechanism as defined in RFC 4422. |
| imapAuthPlain |
This authentication type will use the PLAIN method to
authenticate the client session. This encodes the username and
password in a specific format, but the credentials are not
encrypted. It should be used over a secure connection. The
server must support the PLAIN Simple Authentication and Security
Layer (SASL) mechanism as defined in RFC 4616. |
| imapAuthXOAuth2 |
This authentication type will use the XOAUTH2 method
to authenticate the client session. This authentication method
does not require the user password, instead the BearerToken
property must specify the OAuth 2.0 bearer token issued by the service
provider. |
| imapAuthBearer |
This authentication type will use the OAUTHBEARER method
to authenticate the client session as defined in RFC 7628. This
authentication method does not require the user password, instead the
BearerToken property must specify the OAuth 2.0
access token issued by the service provider. |
Data Type
Integer (Int32)
Remarks
The imapAuthXOAuth2 and imapAuthBearer
authentication methods are similar, but they are not interchangeable. Both
use an OAuth 2.0 bearer token to authenticate the client session, but they
differ in how the token is presented to the server. It is currently preferable
to use the XOAUTH2 method because it is more widely available and some
service providers do not yet support the OAUTHBEARER method.
Changing the value of the BearerToken property will
automatically set the current authentication method to use OAuth 2.0.
