How can I protect my Discord account if I use a second account?

Hello Community,

I have a theoretical situation where I want to protect my primary Discord account while using a second account. Here are the details:

– I have a Discord account that I use regularly.

– Now I've created a second account on a different PC. There are no visible connections between the two accounts.

– When I use the second account, I don't use my home internet, but a public Wi-Fi network and an additional VPN service.

My question now is: What can I do to protect my first account so that it is not associated with my home network when I use the second account at home with my internet network?

I'd like to know how I can use the second account at home with my internet connection or via my mobile hotspot without risking my first account being linked to my home network. Are there any special measures or tips I should consider?

I look forward to your answers and thank you in advance for your help!

Best regards!
