I’ve been running Home Assistant for three years. It’s port forwarded on default port 8123 via a reverse proxy in a dedicated VM serving it over HTTPS and is accessible over ipv4 and ipv6. All user accounts have MFA enabled.
I see a notification every time there’s a failed login attempt, but every single one is either me or someone in my house. I’ve never seen a notification for any other attempts from the internet. Not a single one.
Is this normal? Or am I missing something? I expected it to be hammered with random failed logins.
Yes it is completely normal. The Internet is almost but not quite as bad as security wonks claim. Especially since you’re not on the default port, most scanners don’t have the programming to attempt on Home assistant. Most of them are built for more common exploits.
If you look at your proxy logs, you’ll see attempts at various random paths, but those should all be 404 or 403s.
