Solution 1:

You should be encrypting login creds in your backend.

I recommend Crypto-js. There are instructions for both client side and server side.

Solution 2:

Client side: you can use some of the functionality of crypto-js. Also, you will most likely not be able to use it later on because while encrypting, a "salt" would be added to your variable and hashed together with it - rendering it a compare only value (using the hash comparing function)

It is advisable to encrypt data on your back-end though.
