You appears to be a guy I can trust, Where and how do I create a seed for my wallet?
Happy to be helpful!
The wallet used to have a seed generator, but was removed in the last update because of security reasons, anyway you can still use another randomizer to generate the seed, every seed with the following properties is valid and accepted:
81 characters, capital letters and the number "9" (other numbers are not accepted)
Be careful to properly store your seed, since it is the backup/private key for your balance. In IOTA you can lose your PC, lose your wallet, lose your server but as long as you have your seed you are fine.
