I opened an account a few weeks ago.
In logged in a few times, and had my Firefox remember the password.

Earlier today, I wanted to check whether the money I’ve been expecting had arrived. I tried to login, did so - but instantly there appeared on the screen a request for me to change the password (for “security reasons”). I didn’t have the time to do so, because something else demanded my full attention. So I just closed the browser and went about my business. (No new settings were saved - that I know 100%).

A few minutes ago, I returned to the website and tried to login. No way: it doesn’t recognise my password anymore. Of course I did not mistype it - plus the browser had filled the form automatically (I live alone, so it’s no problem). Still, I checked it, rechecked it, kept trying… all to no avail.

Now I have only one try left before they “lock” my account - again, for security reasons - and I don’t know what to do because there is no way that the password would have been misspelled or changed.

So I requested a new password. I entered my postal code and my date of birth.

Now it said my data weren’t correct.

I retried.
Nothing.

I thought maybe I had made a mistake while selecting the dates when I registered - so, panic stricken, I started going through the entire decade; then I tried different birth dates (day) - basically just guessing what the possible error might have been.

But there had been no error in the original registration form - of that I am sure.

Which means that now I would have to send them a “legible” copy of some identification paper, abd…

It’s just not worth it.
I understand and respect their high regard for security.
But it would do them good to pay a bit more attention to their own “bugs”, too…
