Autofill code gets 'invalid'

edited March 2023 in F-Secure ID Protection


I recently moved from Key to ID protection.

As I tried to install the extension in Firefox I can't get it to work

as the code I get from my ID protection (windows) app gets an 'invalid' message.

How do I solve this?

    Hi @JvdK

    Welcome to our Community page. Thank you for your post.

    First, you would need to verify check if the Firefox browser is up to date:

    1. Open Firefox 
    2. Click on the Menu in the upper right corner
    3. Scroll down to Help 
    4. Select About Firefox 
    5. Check if the browser is up to date

    If the Firefox is up to date, you can try reinstalling the Password Manager by F-Secure extension:

    1. Open Firefox 
    2. Click on the Menu in the upper right corner
    3. Scroll down to Add-ons and Themes 
    4. Click on the three dots next to the Password Manager by F-Secure 
    5. Select Remove
    6. Open F-Secure ID Protection 
    7. Go to Settings 
    8. Select Autofill and click on install Add-on for Firefox to add the extension again

    If the steps above don't help, check if you have the Sync and save data function enabled in Firefox. If yes, follow the steps to disable the function for add-ons:

    1. Open Firefox and login to your Firefox account
    2. Go to Settings and select Sync from the menu on the left-hand side 
    3. Click on Change and untick the box Add-ons in the Choose What To Sync window 

    In case the steps above don't solve the issue, proceed clear all the browser history and cookies. If clearing the browser history and cookies didn't help, you can attempt to refresh the Firefox browser as described here

    Note: Refreshing Firefox browser will remove your extension data and preferences. You may need to add the extensions back after refreshing.

    Kindly go to this link as a guide to install and enable autofill on your browser Installing and authorizing the autofill browser extension | ID PROTECTION | Latest | F-Secure User Guides

    Kindly let me know if this helps.

    Thank you and stay safe.

    Thank you!

    It took all the way to the complete 'refresh' of my firefox for it to work,

    but that was the solution.
