I have my trusty raspberry pi 3b+, 4 years old now and been on 24/7 as a bit torrent box for 3 of those years. Never had it crash once other than deludge gtk having more leaks than a sieve.
I use one on desktop.
For me as pong as the passwords are stored locally or at least end to end encrypted if stored online, then its secure enough. Assuming that the master password is secure.
