Electrum: 2 Wallets showing same Transactions I hope someone can explain, if it's dangerous that i have 2 wallets and both showing the same transactions, the first one has a password for the seed and i can't remember it, the second one not. I also can't remember what i have done and why i have 2 wallets.

If someone can explain me what to do or/and how i can setup a new fresh password-protectet wallet in electrum with all my transactions, would be great.
This would help me to achieve a better technical-understanding for bitcoin and electrum-wallet.
thank you
The only important thing is the seed (the seed words). With it, you can create copies of the Electrum-wallet with or without password. So you could have the same wallet on a PC desktop without password and on an Android phone with a password. (Note that the Android-client also forces you to enter a PIN code.)

I assume you created a new Electrum-wallet, password-protected it and then imported the same Electrum-wallet again (using the seed), without password. You can safely delete the one with password as long as you are very sure they are indeed the same. Perhaps double-check the different Addresses (both Receiving and Change) before you do this. (But this might be hard since you forgot the password?) As long as you are sure you only have one seed that you used for both wallets, you can safely delete one of them. They are surely the same wallet.
