Thank you for contacting us about this, and I'm sorry for the issue you are experiencing. I'm not sure what's happening here, but it sounds like you are trying to create an account rather than signing in to an existing account. This is something many of our German customers have run into because the Sign In and Sign Up buttons on Android mixed up. Are you by any chance running your device in the German language? If you are, can you try tapping the other button when trying to sign in to your "firstname.lastname@example.org" account?
If you are not running your device with the German language, can you let me know why you think mSecure has switched your username to "email@example.com"? I checked for an account using that email address, but I couldn't find one.
Thank you for the screenshot Hellen. It looks like the 13 is 2013, which helped me find your account. You actually have two accounts in our system. One has the email address "firstname.lastname@example.org" and it was created back on March 31st of 2018. The other account has the email address "email@example.com" and was created back on June 19th of 2021. You can use either of those accounts, but you will need to choose one or the other. After you choose one, I can rename the other, then you can reset the app on whichever device is needed to sign in to the correct account.
To clarify, we don't change the usernames of accounts unless that's asked for first, and neither does the mSecure app. Also, we don't create accounts for customers, so the only way you have two accounts is if you created them when setting up the mSecure app. It's also possible to create an account when making a purchase on our website. At any rate, we'll get everything working as it should.
What I need first is to know which device has all your data totally up to date. After you determine that, I need you to go in to the Account Settings for mSecure on that device and tell me which email address you see. If it's a phone or tablet, then you'll open mSecure, tap the menu icon in the top left, tap Settings, and then tap Account Settings. You'll see the email address for the account in that screen.
No problem at all Hellen! Please let us know should you need further assistance.
