1. Authenticatior App (Recommended):Using an authentication app on your smartphone, such as Microsoft Authenticator, offers a secure and convenient way to authenticate your login attempts. This method generates time-based one-time passwords (TOTPs) that are unique for each session, providing an extra layer of security. It doesn't require a network connection during login, which makes it resistant to phishing attacks and ensures access even in areas with poor network coverage.

2. Phone: Using your phone as an MFA method involves receiving a verification code via text message or call during login attempts. While this method is commonly used, it's worth noting that SMS-based verification is less secure than other methods due to the potential for SIM card swapping and interception of text messages.
3. Alternate Phone: Adding an alternate phone number provides an extra layer of redundancy for receiving verification codes. This can be useful if your primary phone is unavailable or you're in a location with limited network coverage
4. Email: Using email as an MFA method involves receiving a verification code in your email inbox. While this method is familiar and easily accessible, it's important to note that it may be less secure compared to other methods due to potential email account compromise.
