I added Lockwise from google store but used the wrong e-mail address. Specifically I used a g mail address, which I have discontinued using. My preferred address is at Yahoo.com. on my Firefox Browser on my desktop machine.. I'm not used to smart phones, but wlil be traveling where I will need the addresses and pass words of my accounts to do business. Apparently, Lockwise would be the best solution to supply me with that information when I need it. But I can find no way to change thee current e-mail address for the product.
