If you want privacy, sadly, you will have to pay. I am currently using Proton Pass (special offer 1$ monthly), you get a good password manager, plus unlimited email aliases.

Proton is also known to be one of the best Email Providers based on good privacy.

Trasmission never worked well for me, on the other hand qBittorrent did the job perfectly.

QBittorrent has been my torrent Client for 4/5 years at this point, never having problems. It works on my Steam Deck too (Arch).
