How to Use PayPal, Venmo, and Cash App Safely — A Senior's Guide to Digital Payments

The short answer: Yes, you can use PayPal, Venmo, and Cash App safely — but only if you follow a few firm rules. The biggest mistake most people make is treating these apps like a bank. They are not. Money sent through a payment app is often gone for good if you send it to the wrong person or fall for a scam.

This guide walks you through everything you need to know: how each app works, what scams to watch for, which security settings to turn on right now, and what to do if something goes wrong.

What These Apps Are (and What They're Not)

PayPal, Venmo, and Cash App are all digital payment apps. They let you send and receive money from your phone or computer without writing a check or handing over cash.

Here is a quick breakdown of each:

PayPal is the oldest and most widely used. It is accepted at many online stores and offers some buyer protection when you pay for goods and services.
Venmo is owned by PayPal and is popular for splitting costs with family — dinner, rent, gifts. It has a social feed that shows your transactions publicly by default (we will fix that below).
Cash App is made by Block (formerly Square). It is simple and lets you send money instantly. It also lets you buy stocks and Bitcoin, which opens the door to investment scams.

What they are not: These apps are not banks. Your money in Venmo or Cash App is not federally insured the way a bank account is. And unlike a credit card, there is usually no fraud reversal if you voluntarily send money to a scammer.

The Scams Targeting Seniors on Payment Apps

Fraudsters love payment apps because transactions are fast and hard to reverse. Here are the scams you are most likely to see:

The "Accidental Payment" Scam

A stranger sends you money and then contacts you saying it was a mistake. They ask you to send it back to a different account. The original payment was made with a stolen credit card — so it gets reversed, and the money you sent comes out of your pocket.

Rule: Never send money "back" to someone who accidentally paid you. Contact the app's support instead.

The Fake Buyer or Seller Scam

You sell something online (Facebook Marketplace, Craigslist) and the buyer insists on paying via Cash App or Venmo. They send a screenshot claiming they paid. They have not. Or they overpay and ask you to refund the difference. Same trap as above.

Rule: Confirm the money is in your account — actually there, not just a screenshot — before shipping anything.

The "Family Emergency" Scam

You get a call or text from someone claiming to be your grandchild or adult child. They are in trouble and need money sent right now via Cash App. Do not do it. Call your family member directly at a number you already have before sending anything.

The Impersonation Scam

A message appears to come from PayPal, Venmo, or Cash App saying your account has been suspended or there is suspicious activity. It asks you to click a link and log in. That link goes to a fake site designed to steal your password.

Rule: Never click links in emails or texts about your payment accounts. Open the app directly or go to the website yourself.

Romance and Investment Scams

Someone you meet online — through a dating site, Facebook, or a game — builds a relationship over weeks or months, then asks you to send money via Cash App or asks you to invest in something through the app. These are almost always scams.

Security Settings to Change Right Now

You do not need to be tech-savvy to lock down these apps. Here is exactly what to do for each one.

PayPal

Turn on two-step verification. In Settings → Security, enable two-step verification. This means a scammer needs your phone as well as your password to get in.
Check your linked bank account. Only link one bank account — the one you actually use. Remove any others.
Use "Goods and Services" when buying. When paying a business or someone you do not know well, select "Goods and Services" at checkout. This gives you PayPal Purchase Protection. Never use "Friends and Family" for a purchase — that waives all protection.

Venmo

Make your transactions private. Tap the menu (three lines) → Settings → Privacy → set to "Private." By default, Venmo shows your transactions publicly. Scammers use this to find targets.
Turn on Face ID or fingerprint lock. This prevents someone who grabs your phone from opening the app.
Only connect with people you know. Do not accept friend requests from strangers on Venmo.

Cash App

Enable Security Lock. In the app, tap the profile icon → Security & Privacy → Security Lock. This requires your PIN or biometrics for every payment.
Turn on notifications. Enable push notifications and email alerts for every transaction so you see activity the moment it happens.
Do not use Cash App for purchases with strangers. Cash App payments to individuals have no buyer protection.

Five Golden Rules for Safe Digital Payments

Only send money to people you know in real life. This is the single most important rule. If you have never met someone in person, do not send them money through any app.
Slow down. Scammers create urgency — "send now or lose your account," "my flight is in two hours." Any pressure to act fast is a red flag. Pause. Call someone you trust.
Confirm payment in the app itself. Never trust a screenshot or email as proof of payment. Open the app and check your balance.
Do not mix personal and business payments. If you sell things online, use PayPal's Goods and Services option — not Venmo or Cash App, which are designed for personal use.
Keep your app updated. Security patches come through updates. Turn on automatic updates on your phone so you are always running the latest, most secure version.

Using Public Wi-Fi With Payment Apps? Read This First

If you are at a coffee shop, library, or airport and you use a payment app on the public Wi-Fi there, you could be at risk. Public Wi-Fi is not encrypted, which means someone nearby with the right tools could potentially intercept your data.

The easiest solution is a VPN (Virtual Private Network). A VPN encrypts your internet connection before it leaves your device, so even on a café's network, your banking and payment activity is private.

NordVPN is one of the most widely recommended VPNs for everyday users. It has a simple one-tap button to connect, works on phones, tablets, and computers, and offers a 100% discount on the first month so you can try it without commitment.

For seniors who use digital payment apps regularly, having a service like Aura running quietly in the background adds an important layer of protection that no app setting can fully replace.

What to Do If Something Goes Wrong

If you think you have been scammed or notice a payment you did not make, act quickly:

Open the app and try to cancel the payment. In PayPal and Venmo, you may be able to cancel if the recipient has not yet accepted the funds. Cash App payments are typically instant and cannot be canceled.
Report it in the app. Every major payment app has a "Report a Problem" or "Dispute" button. Use it.
Contact your bank. If your bank account or debit card is linked to the app, call your bank's fraud line immediately.
Report it to the FTC. Go to reportfraud.ftc.gov. Your report helps law enforcement track patterns and stop scammers.
Tell someone you trust. Scam victims often feel embarrassed and stay quiet. Do not. Reporting it — to family, to your bank, to the FTC — is how you protect yourself and others.

The Bottom Line

Digital payment apps are convenient, and millions of people use them safely every day. The key is treating them differently than you would a credit card. There is no "fraud department" to call and get your money back when you voluntarily send it to the wrong person.

Stick to the people you know, slow down when anyone creates urgency, keep your security settings locked down, and consider using a VPN on public networks and an identity monitoring service in the background.

Those three layers — good habits, a VPN, and account monitoring — cover the vast majority of risks that trip up seniors using payment apps today.
