If you use KDE Connect, your clipboard history immediately goes to your phone's clipboard :)

macOS/ios can also share clipboards for awhile now.

For KDE Connect, does the phone have to be an Android or ?

KDE Connect works on macOS, Windows, Linux, Android and iOS

KDE Connect exists on both iOS and Android, though some functions like text messages aren't available on iOS.

KDE doesn't have infinite clipboard history yet, like the GPaste extension for GNOME Shell has.

I'm fine with ~250 entries (which I configured), plus search. I don't prefer to have "forever" files which grows all the time.

I found out that being able to let go of things relieves a lot of load over one's proverbial and literal shoulders.

CopyQ works for forever history for me, it also doesn't save copied passwords, which is nice.

How does it detect passwords? Usually those are just plain-text when copied.

Either way, I think it is better to not copy passwords to the clipboard or the selection, but store and transfer them via password-manager/browser/etc APIs.

With KDE on Wayland, there is a clipboard hint MIME type `x-kde-passwordManagerHint` for passwords that clipboard managers can choose to drop.

Not too much support out there, but at least some important things do:

At least in my experience, it works with the password and clipboard managers I use, and even some command-line utilities like wl-clipboard.

Wish it was a protocol-level setting, though, instead of something KDE specific and honored at the application level.

More like, almost 3 decades.
