A new window or page will appear, prompting you to log into your PayPal account. Click in the box labelled “Email” and type in the email address associated with your PayPal account. Then, click in the box labelled “Password” and type in the password that you picked to protect your PayPal account. Finish up by clicking Log In.
Once you’ve logged into PayPal and authorized it as a payment method for the particular website that you’re on (in this case, eBay), you will see your default payment option for PayPal appear. Click Change (or the arrow icon highlighted here) if you wish to change the account that PayPal will use to pay for your purchase, and then click the button beside the account that you want to use (in this case, I have my bank account selected, but I could choose my credit card instead).
Note that if you have transferred any money to your PayPal account balance, PayPal may automatically use any money there instead of allowing you to choose which linked account to pay with (or it may give you a choice anyway).
After you’ve selected PayPal as your payment option and selected which (linked) account on PayPal will be paying for your purchase, all that’s left to do is check the rest of your ordering information (shipping options and addresses, rewards and coupons, etc.). If everything looks good, just click Confirm and Pay.
That’s how to pay with PayPal while shopping online! It’s just that easy!
