EncryptPad VS qTox

Better if it's encrypted. I use Encryptpad[0] to store such notes.

I would also take the further step of using a text editor that supports encryption, so that even if an attacker can read files from your computer are using the USB stick, it will still be protected. EncryptPad looks like a good easy to use option, personally I use gVIM, but it's a bit technical. EncryptPad uses industry standard GPG encryption, so the files can be read on Mac and Linux can also, if you ever change OS or collaborate with a peer on the project. They have a nice tutorial here.

I use encryptpad (https://evpo.net/encryptpad/). It allows for symmetric encryption on your local machine and comes with a decent text editor. No cloud storage functionality

Encryptpad is exactly like Notepad with encryption.

As someone else mentioned, Cryptomator is a great option for this, and probably easier. Encrypt Pad can work also. These solutions work differently. Cryptomator gives you an encrypted drive where you can store many files, whereas Encrypt Pad will just encrypt a bunch of text. You can then safely save the encrypted file anywhere, such as your email.

You can also use an encrypted notepad, like EncryptPad. This will password protect the text file as well. Then you have the text file password, OneDrive 2FA and Veracrypt protecting your seed phrase. Good to have if you forget to delete your seed phrase file off your PC. It's still protected even in storage.

Would EncryptPad be enough for your needs?

If you go to https://github.com/qTox/qTox You will see the following: "Due to a lack of resources, qTox is no longer maintained. If someone with provable C++ experience and sufficient resources to maintain qTox wants to take over I'm happy to discuss that." So is someone going to "take over"? I really like qTox & would hate to see it go.

qTox https://qtox.github.io/ There is an android variant called aTox, not sure about mobile IOS.

Maybe something that uses the Tox network? Maybe qTox: https://qtox.github.io/

Qtox(p2p messaging?) failed: You can send files, but it looks like you can only open folders to look for files to send, not send folders themselves.

Tox (anonymous too, if routed through Tor) [clients like qTox might not be the "sexiest", but they are small and can be used almost anywhere]

What is Google? https://qtox.github.io/

Qtox does all that, even if screen sharing was a bit obscure years ago. Qtox won't work on iOS but there is an Android release. Big advantages: no server required, easy to use, secure, open source.
