Is a free credit score app that asks for my bank login details safe to use?
Only if the app is regulated and uses an FCA-authorised open banking connection. Unregulated apps that store your login credentials pose a serious security risk.

Explanation
Many personal finance apps offer free credit score monitoring and budgeting features that require connecting to your bank account. The safe way to do this is through open banking, a regulated framework where you authorise a connection through your bank's own interface — you never share your banking password with the third-party app. Fraudulent or poorly designed apps, however, ask you to enter your actual bank username and password, which they store and potentially misuse. In the UK, any app using open banking must be FCA-registered. Apps that ask you to enter your bank login rather than redirecting you to an official bank authorisation flow should not be used. Always check the app's registration status and read the data policy before granting access.
The design difference is easy to check in the moment it matters: a regulated connection hands you to your own bank — its app or login page, with your bank's own authentication — to approve a described, limited, revocable access, while a credential-harvesting app presents username and password boxes inside its own interface. The former never learns your password; the latter exists to learn it. Since your bank's interface is one you know well, the imitation is usually detectable if you are looking. Whenever the flow feels wrong, stop — no free score or budgeting feature is worth your banking credentials.
Common red flags
- App asks you to enter your bank username and password directly rather than redirecting to a bank authorisation page
- App is not listed on the FCA register or equivalent for your country
- Privacy policy is vague about how your data is stored and shared
- App was downloaded from outside the official app store
What to do now
- Only use apps that connect via your bank's own authorisation page using open banking
- Verify the app's FCA registration at register.fca.org.uk
- Revoke any previously granted bank connections you no longer use through your bank's settings
- Change your banking password immediately if you entered it on an unregulated third-party site
Frequently asked questions
Is giving my bank login to a budgeting app ever acceptable?
No. No legitimate regulated app asks for your full bank login. They use open banking, which only ever asks you to confirm access through your bank's own interface without sharing your password.
What does revoking open banking access actually do?
It cuts off the app's data connection at your bank's side, immediately and without the app's cooperation. Your bank lists active connections in its app or online banking settings; reviewing that list occasionally and removing services you no longer use is good routine hygiene.
