Hi! I see you're having trouble logging into your Santander Portugal app. To help you better, could you please tell me:

- Are you trying to log in via the mobile app or web browser?
- What exactly happens when you try to log in? Do you get an error message?
- Have you already tried any steps, like restarting the app or checking your internet connection?

Once I have a bit more information, I can guide you through some tailored steps to fix it. Meanwhile, one common fix for recent login problems with Santander Portugal app users is to ensure your app is updated to the latest version (1.7.2 or newer), as an update was released recently to solve login issues.

Could you check if your app is up to date? On Windows 10, if you are using a web browser, please confirm which browser and version you are using as well.

Looking forward to your reply!

via app and web browser both

Thanks for letting me know you're having login issues both via the Santander Portugal mobile app and the web browser on your Windows 10 device. Let's tackle these one step at a time to get you back in smoothly.

Step 1: Check Your Internet Connection and Browser Compatibility
- Make sure your internet connection is stable and working well.
- For the web browser on Windows 10, which browser are you using (Edge, Chrome, Firefox, etc.)? Santander’s online banking works best on updated versions of major browsers.

Step 2: Clear Browser Cache and Cookies (for web login)
Sometimes, stored cache or cookies can cause login errors. Try clearing these:
- In your browser’s settings, look for “Clear browsing data” or similar.
- Clear cache and cookies, then restart the browser and try logging in again.

Step 3: Update the Santander Portugal App (for mobile)
If on mobile, please ensure the app is updated to the latest version. The most recent Santander app is designed for secure and smooth login and management of your finances1 2. If you already have the latest version, try uninstalling and reinstalling the app.

Step 4: Verify Your Credentials
Double-check that your username and password are entered correctly (pay attention to uppercase, lowercase, special characters).

Step 5: Reset Password If Needed
If you suspect the password might be the issue, use the "Forgot password" option on the login screen to reset it securely.

Step 6: Confirm Secure Device Registration
Santander uses device recognition for security. Have you registered your device as “secure”? If not, sometimes the system blocks access until this is done. You can follow Santander’s process to register your device for push notifications and confirmation codes9.

Step 7: Check for Service Outages
Occasionally, Santander services may be down or under maintenance. You can confirm current service status on Santander Portugal’s official website or social media.

Could you please try these steps and let me know at which point, if any, you encounter trouble or error messages? That will help me guide you further.

Are you satisfied with this approach so far?
