If i download waves keeper, it would need me to copy and paste my 12 or 15 word seed right? But would it ask for a new password to put or do i put the same password i use for the desktop client?
You need to create a new password especially for Waves Keeper. And it doesn't make operations less secure. SEEDs and private keys are encrypted and stored within the extension and cannot be accessed by the dApps and services on the web, giving you peace of mind that your funds are always safe from hackers and malicious sites. Completing a transaction doesn’t require entering any sensitive information.
