It turns out that emoticons are considered a symbol, so they can beef up your passwords and make them more secure in combination with letters and numbers. Here’s how.
In my experience the only one that works with any degree of reliability is YouTube. Even the Netflix one can be fairly intermittent.
Also a lot in the time you'll go away and the hotel you're in will have a smart TV and the software was last updated in 2011 so you have to sign in on the device.
I've had to manually type in passwords on a TV several times in the last few months because sometimes the login for even the biggest brand-name services is just broken.
