Huge amount of login attempts / 2FA

### Prerequisites

- [x] I have checked the [Wiki](https://github.com/AdguardTeam/AdGuardHome/wiki) and [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions) and found no answer

- [x] I have searched other issues and found no duplicates

- [x] I want to request a feature or enhancement and not ask a question

### The problem

Hey AdGuardTeam,
I am running AGH on Ubuntu 26.04 server in a public environment and I am getting a huge amount of login requests in the journalctl log, but without any description of the username, nor the ip from which the user is coming from. Here is an example line in the logs:
[error] auth: retrieving user from request err="getting user from request: login attempt blocked for 43m2.844831183s"

### Proposed solution

Can you please provide the logs to display ip and username in a future version for getting them banned?

### Alternatives considered and additional information

And besides this, I have another question: Is it possible to implement a two-factor authentication in the web-gui, for example with Google Authenticatior for a bit more security? That would be great. Thanks in advance.
Best regards
