I recently recieved an e-mail from “[no-reply@auth0user.net](mailto:no-reply@auth0user.net)” which alerted me of “We have detected suspicious activity on your Auth0 account .”

Below was the text:  
Auth0 detected an excessive number of failed login attempts from one or more IP addresses.  
To diagnose the problem, filter tenant logs by “Blocked IP Address.”  
The IPs that produced the suspicious activity have been blocked.  
Individual IPs can be unblocked using [Auth0’s Management API.](https://auth0.com/docs/api/management/v2#!/Anomaly/delete_ips_by_id)

I do find the sender suspicious. Is this spam or a valid e-mail from Auth0

Hi @Sivesind,

Welcome back to the Auth0 Community!

That is the default _From_ field for Auth0 tenants.

Here is an example:

Thanks. That is good to know. When I tried to look up the domain, I did not find any reference to Auth0.
