How can multi-factor authentication (MFA) enhance cloud security?

Multi-factor authentication (MFA) significantly enhances cloud security by requiring two or more verification methods to authenticate users. This layered approach means that even if one factor, such as a password, is compromised, unauthorized access is still prevented because additional factors must be satisfied for successful login. These factors typically include something the user knows (like a password), something the user has (such as a smartphone or a hardware token), or something the user is (like a fingerprint or facial recognition).

The effectiveness of MFA lies in its ability to create multiple barriers that an attacker would need to bypass, thus greatly increasing the difficulty for unauthorized access. Implementing MFA adds a crucial layer of protection, which is especially important in cloud environments where sensitive data is often stored and can be targeted by cyber threats. This makes MFA one of the foundational practices in securing cloud applications and services.
