Microsd Backup of seedphrase?

why is the encrypted password of seedphrase is just 20 digits? assuming 10^20 entropy, it is significantly less safer compared to 128bit,
because of this, 1 cannot mobilize the backup files onto Hot devices( Even though its not recommended), Coldcard Q on the other hand generates 12 words phrase for backup and even provides custom option for encryption password
