I recently arrived in Spain and opened an account at Cajamar bank. The teller gave me a stack of documents, including a contract for online banking with an initial username and password. I was a bit confused at the time, but after some research at home, I figured out how to log in. I’ve seen some people on the forums asking about this, so I decided to put together my experience to help other newcomers who’ve just gotten their cards.
PC Web Browser Login
Let’s start with the most common method: logging in through a web browser on your computer. This version offers the most comprehensive features, making it easy to check your transaction history, make transfers, and more. The first step is to go to the official Cajamar website. On the homepage, you’ll usually find a prominent button in the top-right corner labeled “Banca Electrónica” or “Acceso Clientes.” Click on it, and you’ll be taken to the login page.
You’ll need to enter two pieces of information: Usuario (Username) and Contraseña/PIN (Password/PIN). You can find both on the contract documents the bank gave you when you opened your account. The ‘Usuario’ is typically a combination of letters and numbers, and the initial password is also printed there. After your first login, the system will usually require you to change it to a password of your own choosing. It’s very important to remember this, never keep using the initial password—it’s not secure!

Mobile App Login
Nowadays, most of us use our phones more than our computers, so knowing how to log in via the app is essential. Simply search for “Grupo Cajamar” in your phone’s app store to find the official app. After downloading and installing it, open the app. The login process is nearly identical to the web version, requiring your ‘Usuario’ and password. Once you’ve successfully logged in on your phone for the first time, I highly recommend enabling fingerprint or face ID login in the settings. This way, you won’t have to re-enter your password every time you open the app, which is super convenient and more secure.
Common Issues and Solutions
I’ve compiled a few issues I’ve encountered myself or that friends have asked about. I’ve organized them in a table for quick reference.
| Issue | Solution |
| What if I forget my password? | On the login page, find the option “He olvidado mis claves” or something similar. Follow the prompts to reset your password via an SMS verification code sent to the phone number you used for opening your Cajamar account. If that doesn’t work, the most reliable method is to go to any Cajamar branch with your residence card and ask a teller to help you reset it. |
| First-time login failed? | Double-check that you’ve entered the username and password from your contract correctly, paying attention to case sensitivity. Sometimes the bank’s system isn’t activated immediately—we’ve seen this happen with various services, even those related to Cajamar selling properties. You can wait a few hours and try again, or just go to a branch and ask. |
| Not receiving the login verification code? | Check if the mobile number registered with the bank is correct and that you have a good signal. Sometimes network delays can cause issues, so you can wait a moment and try again. |
Cajamar’s online banking and app are quite user-friendly. Once you get past the first login, it’s smooth sailing. I hope this guide helps! If you have any other questions, feel free to reply to this post to discuss, and we can figure them out together. Wishing you all a happy life in Spain!
