Sorry OP, I was trying to do a few things at once. But found this which should be helpful https://vaultwarden.discourse.group/t/installation-for-a-noob/1609
One of the comments provides a step by step guide for setup. If this sounds reasonable, then you could do it all here and you'd have no need for Aegis!
Good to know, I didn't talk about self hosting as it seemed like OP was aiming for it to be through a cloud provider. Its rad Bitwarden has both options and security is top notch either way!
I've used Bitwarden for ages and it fits your needs very well. Sharing the login info will allow the rest of your family to access the passwords and TOTPs too. Bitwarden does charge for TOTP use, but Aegis is amazing to use along with Bitwarden. You could setup Aegis on your device and then, if you wanted someone else to have access, you'd just export the data so they could import it into their Aegis app.
It's quite an easy program to install and it's also cross platform. The fact drives need the softwarenon aNY PC trying to gain access seems like a feature to me. Maybe if you wanted to copy something from the encrypted drive to a friends computer, only then would it be somewhat of a nuisance. But this all ties into me recommending to leave some portion of the hard drive alone. You'd be able to access anything not in VC's space anywhere, while it's also a breeze to download and install VC too.
If things are still the same from ~ June of 2022 then you have a choice between none, Linux Ext2, Linux Ext3, Linux Ext4, and NTFS.
Edit: VeraCrypt utilizes a unique encryption process. Its easy as you just move the mouse around like you went mad, but this produces a highly secure encryption key too. As long as your distro works with NTFS then it seems VeraCrypt can assist to help you encrypt. Otherwise, when Windows is a VM it only can do what Linux allows it to do lol
Depending on your specific situation, it could be a solid option to just jump in to whatever distro covers your needs best and just run Windows in a VM. On a current Linux device which previously ran windows, throw this in the terminal:
sudo strings /sys/firmware/acpi/tables/MSDM
and it will source the old Windows product key. You can also just jot down the key by pulling it up in Windows too. But regardless of how it's handled, it makes the VM setup an easier process for sure!
VeraCrypt is the only company I use when it comes to encrypting external drives. Depending on what distro you use, you'll just have to select the proper file format. Aside from that, maybe encrypt 90% of the drive so there's some space for a few things which you can access without mounting the drive. When you go through the setup in VeraCrypt, it directly asks if the drive will be used with one or different systems, so they got you covered there. You can also find many video walk throughs online to follow along with as well.
Why switch platforms if all your data is still being collected? This just provides another business with your data to sell and possibly have hacked. Sure, Telegram offers encryption, but it's not enabled by default even though they advertise it thoroughly. This demonstrates they're taking advantage of peoples desire for privacy simply to increase their user base while making the users + contacts do all the work.
As far as file sharing, with ProtonDrive I can use any messaging service and send a 500GB file if I wanted, fully encrypted with password protection and an expiration date. Telegram keeping the files forever doesn't seem like a benefit either.
Cryptpad.fr is a fantastic full replacement for Google Office Suite. Open sourced, encrypted, but only comes with 1GB of storage on the free plan. You can pay to add more and its reasonably priced. It provides excell, powerpoint, and word. I like using board.net at times too. It's FOSS as well but only provides a word equivalent. A little more straight forward in my experience for others.
Okular is amazing, this paired with Libre Office for PDF creation is how I do PDF production and editing. Okular has somewhat limited editing, so when converting scans/photos into a PDF I use KolourPaint for more detailed editing. It allows me to remove, add, or edit anything in a scan/photo before it's converted into a PDF by Libre Office.
Screw shower thoughts, where's shitter thoughts!?!
Yep, you sure are lol, I edit the previous comment and added a Debian install guide for Vaultwarden. My apologies for the mix up.
