Password managers

What is a password manager?

A password manager is an application that securely stores your login credentials (email addresses, usernames, and passwords) so you don't have to remember them all. It can also generate strong, unique passwords for you.

Password managers come in different forms:

Standalone apps - Dedicated password managers like Passbolt (opens in a new tab) (Luxembourg-based, open source), Bitwarden (opens in a new tab), KeePass (opens in a new tab), or Proton Pass (opens in a new tab) that work across all your devices and browsers.
Browser built-in - Most browsers (Chrome, Firefox, Safari, Edge) have a built-in password manager that offers to save and autofill your passwords.
Operating system built-in - Apple iCloud Keychain (opens in a new tab) (macOS/iOS), Google Password Manager (opens in a new tab) (Android/Chrome), and Windows Credential Manager (opens in a new tab) can store passwords at the system level.

How password managers work with LuxID

When you sign in to LuxID at login.luxid.lu (opens in a new tab), your password manager may:

Offer to save your LuxID credentials after you sign in for the first time.
Autofill your email and password on future visits, so you don't have to type them.
Suggest a strong password when you create your account or change your password.

LuxID follows the web standards that password managers rely on, so it works with the vast majority of them - there are no restrictions on using autofill or generated passwords. If you find that your password manager does not work correctly with LuxID, let us know.

How to recognise a password manager interaction

Many people use a password manager or browser autofill without realising it - it was switched on by default, or saved a password at some point and now fills it in quietly. If you see any of the following, it's your password manager or browser, not LuxID, interacting with you:

A coloured tint on the email or password field - often pale yellow or light blue. This shaded background is the clearest sign that your browser or password manager filled the field for you, rather than you typing it. Each browser uses its own colour, so the exact shade varies.
Your email and password already filled in when the sign-in page loads, before you type anything. If the fields are populated on arrival, autofill did it.
A pop-up near the sign-in fields offering to fill in your credentials or save new ones.
A small icon inside the email or password field (often a key, lock, or the password manager's logo).
A notification bar at the top or bottom of the browser asking "Save this password?" after you sign in.
An overlay or dropdown listing saved accounts when you click the email field.

These are normal browser or password manager behaviours. LuxID itself does not display pop-ups asking to save passwords, and does not colour the sign-in fields.

Which one is filling my password?

If a password appears but you are not sure where it is stored, check in this order:

Your browser's built-in manager - look in the browser settings (search for "Passwords" or "Autofill"). If login.luxid.lu is listed there, the browser is filling it.
A password manager extension - look for its icon in the browser toolbar (top-right in most browsers). Clicking it usually shows the saved LuxID entry.
Your operating system - on a phone or tablet, the fill prompt may come from Apple iCloud Keychain (opens in a new tab) or Google Password Manager (opens in a new tab) rather than the browser.

Knowing which one holds your password matters when you change it: you need to update the saved copy in the same place, otherwise it will keep filling in the old one (see Common issues and troubleshooting below).

Unique passwords - You can use a different strong password for every service, including LuxID, without having to remember them all.
Stronger passwords - Password managers generate random passwords that are much harder to guess than ones you create yourself.
Less typing - Autofill saves time and reduces the risk of typing errors.
Phishing protection - Many password managers only autofill on the correct website, which helps you avoid fake sign-in pages.

Common issues and troubleshooting

Make sure your password is saved for the domain login.luxid.lu. Some password managers may have saved it under a different URL.
Check that the password manager browser extension is enabled and unlocked.
Try clicking inside the email or password field - some password managers need this to trigger autofill.

Password changed on one device but not updated on another

This is one of the most common issues. If you change your LuxID password on one device, your password manager must sync the updated password to all your other devices. If it doesn't:

You will be locked out on any device that still has the old password saved.
You may see "incorrect password" errors even though you're sure you typed it correctly - this is because your password manager is autofilling the old password.

To fix this:

On the device where the password was changed, open your password manager and confirm the new password is saved for login.luxid.lu.
Make sure sync is enabled in your password manager settings.
On the other device, wait for the sync to complete, or manually update the saved password.
If sync is not available (e.g., you use a local-only password manager like KeePass without cloud sync), you must manually update the password on each device.
