Incorrect password cannot be changed

Occasionally for unknown reasons, when I initiate a call, Linphone-3 asks me for a password for an account it's been using for ages without asking.
If in responding I enter an incorrect password, then whenever after I initiate a call I get a voice saying "incorrect password" (from the provider, freephonline.ca, I guess). Instead, I should be prompted for the correct one.
Now, if I edit the account info, there is nowhere to reset the password (nor to toggle whether it should be saved or not). The only way to reset it is to choose to erase ALL passwords for ALL accounts.
there should instead be a way to erase only the password of the displayed/current account.

I fear someone may call this a feature request.
