I’m a bit confused; I thought forced password changes were important, but I don’t see how they directly stop brute force attacks.

I’m leaning towards multifactor authentication as the best option here, but I wonder if the password manager could play a role in making passwords stronger.

I practiced a similar question, and I feel like the delay between authentication attempts could help too, but it might not be enough on its own.

The answer has to be the multifactor authentication. That's the only way to truly secure the account from a brute force attack.

Forced password changes every 6 months? That doesn't seem like it would really stop a brute force attack. I'm going with the delay between attempts.

I'm not sure about this one. A password manager could help, but I don't think that's the main thing you'd need to stop a brute force attack.
