[!warning] Firstly, always utilise anonymous email accounts to keep your personal and cryptocurrency accounts separate. Proton Mail is an excellent option. The paid version allows you to create multiple aliases within one account, you can try the paid version free for a month.
1. Use a VPN
Both recommendations support payment in crypto.
- Proton VPN - includes Proton Mail

2. Password Manager
3. Password Generation
Never use the same password. The best option is to let your password app generate a password for every time you sign up somewhere.
4. Seed phrase/private key storage
[!info] This is a Bitwarden alternative, some people like to keep their regular passwords and wallet seeds separate.
You can use encrypted storage if you want to store your keys digitally in the cloud. The easiest solution is Proton Pass. You create a vault, which is like a folder where you can just add text files or excel sheets with your private keys and other sensitive data.
A more advanced solution, suitable for seeds you almost never need, is a strongly encrypted vault (with Cryptomator) stored in the cloud.
