Nobody should be using an online password manager; especially when it comes to sensitive information like private keys. There is no reason to trusting intermediaries when you have cryptography. Install KeePassXC on both your main computer and your mobile. Use a strong password to encrypt both password databases. Back them up. Both the databas(es) (digitally) and the encryption pass (on paper).

Hello,

I'm also very interested in this topic. Can people please post new updates to the list (only for Bitcoin)?
Remember, this post is about EXCHANGES, not software wallets.
Let me start by giving my own input:

Kraken: yes, can create multiple deposit addresses
Coinbase: yes, can create multiple deposit addresses
Bitstamp: yes, can create multiple deposit addresses
Bitfinex: yes, can create multiple deposit addresses
Blockchain.com: no, only 1 deposit address

Any more input please?
