Generate 20 Character Password

A 20-character password is recommended for anyone protecting high-value assets: password manager master passwords, primary email accounts, financial services, and enterprise admin accounts. If a single compromised password could lead to significant financial or data loss, 20 characters provides the extra margin of safety you need.

The only practical downside is that longer passwords are harder to type manually on devices without autofill. This is rarely an issue since password managers handle entry automatically. For the rare case where you must type it (like logging into your password manager on a new device), practice typing it a few times after generating it.

With over 130 bits of entropy, a 20-character mixed-type password resists attacks from even state-sponsored adversaries with massive computing resources. No known or foreseeable technology can brute-force this level of entropy. It exceeds the security requirements of most enterprise compliance frameworks including SOC 2 and ISO 27001.

Absolutely. WPA2 and WPA3 support passwords up to 63 characters, so 20 characters works perfectly for wireless networks. Since you typically only enter a Wi-Fi password once per device and can use copy-paste, the extra length causes no inconvenience while providing excellent network security.
