*MFA is a security method that requires users to provide two or more pieces of evidence to verify their identity, such as a password, a code, a token, or a biometric factor3.
*MFA adds an extra layer of protection against ransomware attacks, as it prevents attackers from accessing the Veeam components even if they manage to steal or guess the passwords of the administrative accounts12.
*MFA also helps to prevent unauthorized changes or deletions of backup data, as well as unauthorized restores or failovers of VMs or applications12.
The other options are not as effective or feasible, as they either do not provide enough security, limit the functionality, or disrupt the integration of the Veeam infrastructure.
