I was merely pointing out that the 2FA-email feature was always available to you, but you are choosing not to use it. You said you were confused why Bitwarden doesn’t offer it to free users, but it does.
And yes, if you also chose to ignore Bitwarden’s warning when you setup two-step login to save the recovery codes, then you may be locked out of your account on an un-trusted device. You may also eventually get locked out of your tablet when its ‘trust’ expires and you are required to re-login on the tablet with 2FA.
So, what you should immediately do is go onto your tablet and export a backup of your BW account. If you are currently logged in on the tablet, then all you will require is your master password for the export. Once you have the export in hand (you need an unencrypted JSON format), create a new Bitwarden account and import the file with your vault info, and you can start again from scratch. Once you have confirmed that the new account has your info, then you will need to delete the old account.
Here is a link to a guide on how to best backup your data and your two-step login method:
Please let us know how you make out! Cheers.
