We don’t show secret key in the mobile apps. Your secret key is stored in the web app settings only:
If you forgot your secret key - you can try to restore it using Recovery code.
If you forgot your recovery key as well - we can't help you to restore stellar-lobstr accounts connection. That's the main point of the LOBSTR wallet security - we don't have access to users money.
You should have your recovery code (LOBSTR sends it to a user email by default)
Your Recovery key is connected to only one stellar account and can restore the only account that was connected to your LOBSTR wallet earlier.
To restore Lobstr-Stellar accounts connection you’ll need to reset your password. So, you need to do the following:
1) Make sure, that you saved your Recovery key in process of registration and you have it.
2) Logout from your LOBSTR account
3) Go to Sign In page and find "Forgot password?" button. Or just use this link: https://lobstr.co/password_reset
You'll be asked for recovery key, which we don't have on our side, to make app usage safe for users.
If you did everything correctly and entered Recovery code - stellar account that was connected to your LOBSTR account should have secret key again.
