The most common protocol used for domain authentication is Transport Layer Security (TLS). TLS is a cryptographic protocol that provides secure communication over the internet. It is used to protect data in transit, such as passwords, credit card numbers, and other sensitive information.

The protocol commonly used for domain authentication is the DomainKeys Identified Mail (DKIM) protocol. DKIM is an email authentication method that allows the domain owner to attach a digital signature to outgoing emails. The signature is generated using cryptographic techniques, verifying that the email message has not been modified during transit and that it originated from an authorized domain.
When an email is received, the recipient's mail server can verify the DKIM signature by retrieving the public key from the sender's domain's DNS records. The mail server then uses the public key to decrypt the signature and compare it with the contents of the email. If the signature matches, it confirms that the email was not tampered with and was indeed sent from the claimed domain.
DKIM helps prevent email spoofing and impersonation by providing a mechanism for verifying the authenticity of the sender's domain. It is widely supported by email service providers and is an essential component of email authentication to ensure secure and trusted communication.

The protocol commonly used for domain authentication in Windows environments is the Kerberos protocol. Kerberos is a network authentication protocol that provides secure authentication between clients and servers in a domain environment. It uses tickets to authenticate users and facilitate secure communication within a network.
In a Windows Active Directory domain, Kerberos is the default authentication protocol. It enables clients to authenticate with domain controllers and obtain tickets that allow them to access network resources securely. The Kerberos protocol is based on a trusted third-party model and uses symmetric key cryptography to ensure the confidentiality and integrity of authentication exchanges.
Kerberos authentication in Windows domains typically occurs over TCP/IP using port 88. It provides a secure and efficient method for verifying the identity of users and enabling secure access to domain resources.

The protocol commonly used for domain authentication is the Lightweight Directory Access Protocol (LDAP). LDAP is an application protocol used to access and manage directory information, including user and group authentication data, within a directory service such as Microsoft Active Directory (AD).
When a user attempts to authenticate against a domain controller in an Active Directory environment, the authentication process typically involves the use of LDAP. The user's credentials are transmitted securely to the domain controller using LDAP over a secure channel (such as LDAP over SSL/TLS), and the domain controller validates the user's identity against the stored directory information.
LDAP provides a standardized and widely supported method for querying and managing directory information, making it a popular choice for domain authentication in various directory service implementations, including Active Directory.
