Is copy and paste safe?

@brtsos: The Windows clipboard is not encrypted no matter which app you copy data from. While it's certainly possible to encrypt data before copying it to the clipboard, it will then still be encrypted when you paste it — not particularly useful.

But while I wouldn't call the clipboard "secure", it is safe to use provided you don't have untrusted software running on your machine (which will also have access to the clipboard, since it's system-wide). You can, of course, use 1Password without browser extensions, but using the extensions to fill is more secure than using copy and paste since only 1Password has access to it until it is entered into the webpage — and this is significantly more convenient as well.

I hope this helps. Be sure to let me know if you have any other questions! :)

@brtsos: Instead of drag and drop, passwords can be filled using the 1Password browser extensions (on the desktop version) or the 1Password iOS extension. That way the system clipboard (which all apps have access to) is bypassed completely — only 1Password is used. Cheers! :)
