Recovering password from mailbox app in ios 15

The password for my wife's long time email account on comcast was transferred from an old iphone to a new iphone 12. Her email is viewed and managed through the "accounts" feature, not as a separate app.

The password for the account doesn't show under "passwords" in settings. In fact, there are NO passwords there, I suspect because she doesn't save or autofill passwords on her phone.

We need the password to set up a new computer. We would prefer not to change it because of the collateral issues involved in updating several devices, and because Comcast email is super buggy.

Can this saved password be viewed? It does not show up in the accounts section of settings.

Thanks
