u2f to protect personal data on My giffgaff with 2-step ("2 factor") authentication option for My giffgaff logins

There's a lot of personal data on My giffgaff which members need to keep secure.
Companies like Google, Dropbox, Github (soon PayPal, EBay, Visa, Mastercard, Microsoft and others) support the excellent "FIDO u2f" standard so that users can opt-in to secure logins to their websites.
See this example video for how it works: https://www.youtube.com/watch?v=EVx3QkJ8_J0
... since it was made, Microsoft and Firefox have announced upcoming support in their browsers too.
You can buy the USB keys from many different manufacturers from about £5 (some also work with NFC for tablet and phones without plugging in), and use each key with multiple sites (without compromising privacy).
Google, Dropbox, Github all allow users to add these to their account, and require their use either for every login, or just for the first login from a particular computer.
I've been using one for a couple of weeks now, and I think they're great! Google have reported a more than 75% reduction in unauthorised access to accounts (e.g. via malware etc.) for users who use them.
