Try to change password but "This account recovery session is not valid anymore, please try again"

[。]

Whenever I try to change my password via setting in steam client and choose not to confirm to steam mobile app, verification code to my phone nor my email, It then asks your current account password, having put my password for that does not let me change my password. It says "This account recovery session is not valid anymore, please try again". It's been like this for months and I don't know how to fix this.
Does anyone having this issue?
How do I fix it?

Why do you refuse to verify the change?

I just wanted to test it out if I leave my pc when my acc is still log on, someone who knows my acc password can change my password.

Dont leave a pc without lock when you leave.

Also your goal completely contradicts what you named as "problem".
This does not look right.

It is only possible by telephone or e-mail. Or the support

Then why It asks for my current password? if they want to make only phone or email to verify.

I assume that was the old way, but now as you told us, its not.

Why not verify using mobile/email?

You could tell us, by the results of your tests.
But you should anyway lock a pc when you are not there.

There are many things that can be done if not. Same with phone. If its unlocked when someone holds it they can take several accounts without knowing anything.
