How secure is PayPal? The PayPal site is highly secure. We use industry-leading technology (such as SSL) to keep your information safe.
PayPal automatically encrypts your confidential information in transit from your computer to ours using the Secure Sockets Layer protocol (SSL) with an encryption key length of 128-bits (the highest level commercially available). Before you even register or log in to the PayPal site, our server checks that you're using an approved browser - one that uses SSL 3.0 or higher.
Once your information reaches the PayPal site, it resides on a server that is heavily guarded both physically and electronically. PayPal servers sit behind an electronic firewall and are not directly connected to the internet, so your private information is available only to authorized computers.
On-line merchants never see your bank account numbers or credit card numbers. They only see your email address, date of sign-up, and whether or not you have completed PayPal's Verification process.
PayPal processes billions of dollars in payments each year, allowing us to continually perfect our anti-fraud protections. As a result, PayPal's loss rate is significantly lower than other on-line payment processors.
