Email, encryption, and other protections

Managing your financial identity online is extremely important. Here are just a few ways we help you stay secure.

Email confirmations

Any time you send or receive a PayPal payment, we'll send you an email to confirm the transaction. If you ever receive a confirmation email for a transaction you didn't make, alert us right away and we'll launch an investigation.

PayPal Security Key

The PayPal Security Key gives you a second authentication factor when you're logging in to your account. In addition to your password, you enter a One Time Pin (OTP) that’s unique for each login. These two factors give you stronger account security.

What is it?

The PayPal Security Key sends you a temporary security code via SMS that you enter in addition to your password to log in to PayPal.

How much does it cost?

It’s free to use your mobile phone as your PayPal Security Key. Standard text messaging rates apply when you receive a security code by SMS. Check with your mobile provider for details.

How do I get started?


Data encryption

There are a lot of reasons more than million account holders trust us with their financial info, but data encryption is one of the most important. Data encryption helps keep your data secure with automatic encryption for sensitive information and email communications.

Here's how we do it:

On your computer

When you register or log in to PayPal, we confirm that your browser is running TLS 1.0 or higher, which secures the communication from your browser to

When information is in transit

All of your information is protected by SSL, which ensures that your information is encrypted and can’t be stolen when it's sent across the internet.

On our website servers

Your personal information is stored on our servers and heavily guarded – both physically and electronically. And to give your credit card and bank numbers an extra layer of security, we don’t directly connect our firewall-protected servers to the internet.

All of that said: sending sensitive information (like account numbers or social security numbers) via email is never a good idea. If you need to provide this kind of information, a phone call is best.
