What could possibly...?
I think I prefer to stick to handling my own money, thanks.
Physical debit card for debits
Separate credit card with very limited spending limit for online transactions (but prefer Paypal)
Paypal only from one computer, requires password every time, and uses 2FA
No other credit cards
Bank transfers online - one computer only
And I'm sure some toerag will still manage to relieve me of my dosh one day - but I'm not going to make it easier for them with Google Pay!
