Yes, you can update your password on LocalCoinSwap as long as you remember your old password.
To do so:
- Log in to your account
- Go to Settings -> Security -> Change Password
Given that accounts on LocalCoinSwap are client-side encrypted, it is not possible to reset a forgotten password. This is the same technology that prevents the platform from being able to access the funds held in your non-custodial wallets or their private keys.
