Be careful if you are using a Ledger hardware wallet. Be careful of messages in which someone asks you for private keys or to log in via SMS or email. These are scammers who have been impersonating Ledger's team in recent days.
The Ledger wallet is a so-called "cold" offline hardware wallet that allows you to store Bitcoin (BTC), Ethereum (ETH) and many other altcoins. Producer Ledger claims its product is unhackable. The main advantage of Ledger wallets is the ability to store private keys offline. This ensures the highest level of security and means that we do not have to worry about losing our funds.
