Choosing a fintech app: a checklist
Before you trust any app with your money or data, run it through these questions.
- Is the company licensed and regulated where I live?
- Are my deposits or funds protected if it fails?
- Does it offer two-factor authentication?
- What are the real fees, including exchange-rate margins?
- What data does it collect, and does it sell or share it?
- Can I reach a human if something goes wrong?
Digital security checklist
The habits that protect the vast majority of people from fraud.
- Use a unique, strong password for every financial account
- Turn on two-factor authentication everywhere it's offered
- Never share a one-time code, PIN or password with anyone
- Keep your phone and apps updated
- Be suspicious of urgent, unexpected messages about your money
- Verify contacts by opening the official app, not by clicking links
Spotting a scam: red flags
- Pressure to act “right now” or lose out
- Requests to move money to “keep it safe”
- Guaranteed, too-good-to-be-true returns
- Anyone asking for your codes, passwords or remote access
- Payment demanded only in crypto or gift cards
Frequently asked questions
Is my money safe in a neobank?
If the neobank is properly licensed and your deposits fall under your country's protection scheme, it can be as safe as a traditional bank. Always confirm that protection before depositing. See the digital banking guide.
Are digital wallets safer than physical cards?
In many ways yes, because tokenization hides your real card number and payments are locked behind your fingerprint or face. Our payments guide explains how.
Do budgeting apps sell my data?
It varies. Reputable apps are transparent about data use; others rely on it. Always read how an app handles your information, our budgeting apps guide shows what to look for.
Is a robo-advisor right for a beginner?
For hands-off beginners it can be a low-cost, diversified starting point, though your money still rises and falls with the market. Read the robo-investing guide.
How much should I put into crypto?
Given its volatility and lack of protection, a common view is that crypto, if you engage at all, should only ever be money you can afford to lose completely. Understand it first via our crypto guide.
