How do I open a terminal with another user name?

Whenever I open the terminal, I want to login as another user (another_user). I tried putting the below in my .bashrc, but it prompts me for a password everytime I open the terminal.

# in .bashrc
su - another_user

Question: how do I pass another_user's password as a text input in .bashrc so that I don't have to type it every time the terminal opens?

PS: don't worry about security issues.

Thanks.

ด้านล่างใช้งานได้สำหรับฉัน:

echo 'รหัสผ่าน_ข้อความ' | sudo -S นอน 1 && sudo su - another_user

ขอบใจ!
