hello Eleanor,
i just went into the account details section of the easy reader app and told it
to log me out.
it did so and returned me to what must be considered the home page.
if you go down this screen you come to a section which says lig in using google
or your dolphin account.
below this it has google followed by dolphin account.
if i tap on dolphin account it then asks me to enter my email address and
password, and below this is a forgotten my password button.
pete.
