when i was claiming BCH from electron cash, i use seed from electrum wallet with 2fa. now my electron cash wallet using 2fa also.
is the electron cash wallet 2fa = electrum wallet 2fa?
i already got BCH from electron cash. now, can i use electron cash wallet and electrum wallet with the same laptop?
If you're happy that ElectronCash is safe, then there is no reason why you can't use both applications on the same laptop... they install and use different data directories, so there shouldn't be any conflict.
The critical thing is whether or not your consider ElectronCash to be trustworthy... the jury of public opinion still seems to be undecided about this fact right now.
Also, 2FA is broken in ElectronCash, and will remain broken for the foreseeable future...
Someone claiming to be TrustedCoin Admin has stated that they will not be adding support for BCC. If your coins are in a 2FA wallet, you need to restore using 2FA, but disable 2FA when prompted if you want to "keep or disable".
Also, you'll need to be using
the latest version of ElectronCash (now up to v2.9.2) to make MultiSig work... which is what your disabled 2FA wallet will be.
