Can PayPal transfer money automatically from my bank account if I link it in PayPal?
Practically, as an ebay buyer I have never seen any way to keep a balance in paypal and top it off from my bank account under my own control.  It is all automated, and as I seem to recall linking with a bank account or credit card was necessary to get some kind of "confirmed address" status out of Paypal so that eBay sellers would be more willing to trust me as a buyer and know that my shipping address was legitimate.  As a seller, I can keep a balance at paypal from eBay sales and ask for it back in my checking account instead of keeping it in paypal to purchase items later. In terms of advice, in my opinion the paypal transfer limits or how to set them is not the answer needed to protect one's finances in this situation.   In an error or cyberattack scenario, you have to consider the possibility that any limits are exceeded.  When your online activity of any kind is linked to a bank account, any amount in that linked bank account is probably at risk.  It doesn't really matter if it is paypal, or a server rental account, or amazon.  If it can be abused, and it is linked to your bank account, then someone might abuse it and leave you with a bill. That you might be ultimately victorious is of little consequence if someone steals money you really needed right now and the devotion of time and energy to "work the bureaucracy" to get your money back will distract from performance at work or school. So the next step up in protection is to firewall the bank account you use for online purchases from your other bank accounts where your salary is received.  The best way to do it is with different banks instead of merely different accounts, but that is also the most inconvenient for filling the account back up.   Nowadays -- at least in the USA -- at several banks you can open a "free" checking account for a minimum deposit like $500 or $1000 that must stay in the account to be fee free at the end of each month.  Whatever balance you keep in the account you use for your "risky" online transactions will be the maximum that can disappear in an incident, downside being you have to feed the account from time to time to keep it above the minimum as you make purchases.
