I had some trouble getting Vaultwarden connected to my phone and the Bitwarden Windows desktop application. So I created a video on the process.
Hopefully people find it useful.
Umbrel - Vaultwarden setup for Android and Windows
It worked for me to setup the Windows version. But i use a iOS phone still looking for a solution on that… 
Could you try throwing the app port through Cloudflare Tunnel (the app in Umbrel Appstore) instead of Tor? Then, it will probably work on iOS as well.
Yes I ended up doing this and it works now
Could you please explain it step by step. Unfortunately I am waiting since 2 years for a ios guide. Thanks in advance
Is there still no guide for apple devices ?
No, there is nothing for IOS.
This video also maybe out of date due to updates to Bitwarden and especially android security policy.
Damn it would be nice to have more clear and up to date guidelines, I love umbrel but it lacks of App updates and nice Video Guidelines.
Agreed.
I did the guide video above after feeling the same way you do. I just stumbled through the process myself. Using different posts and trial and error, which can be risky.
I wish I was faster and better at making videos, seems to be a good niche in Umbrel / Linux - How to guides.
