Please how do I know which email I have used in my... @KukaiWallet

If you are not sure which email you used to set up your wallet, the best way to find out is to check the pinned message in your wallet. This message will usually contain important information such as the email address used to set up the wallet. Additionally, be aware of fake admins who may attempt to help you with your wallet, but are actually trying to scam you. If you are still unsure which email you used, you may need to contact customer service or the wallet provider for assistance.

Also read the pinned message, it’s a serious warning, fake admin will pretend to help

If you signed in with email only you know which one you used
