Android security questions

[fiafo]

Hi,

How are security credentials/passwords stored on android phones? Are they encrypted or in other way secured in case of i.e. theft, or do I need third-party applications to secure my phone?

For example, if my telephone gets stolen, would it be possible to easily get access to stored browser passwords, my google password, app passwords (e.g. login to cloud services)

Are these in some way encrypted and tied to PIN, unlock code or other are they completely "in the open"?

Thanks for any insight, from someone new to Android!

How do you secure your device? I'm used to using full disk encryption, master passwords etc on the PCs I use, but i do not know how to secure my android device!
