encrypt SD on android

A friend of mine got herself a new Xperia 10 and wants to encrypt the SD card. It seems this option is no longer available - previously there was a "Encrypt SD card" option in settings - but no more. Apparently it was also possible to use the SD card as "Adoptable storage" - but no more.

Is it at all possible to encrypt an SD card on Android (15) or is de-googling the only option?

Encrypting the SD card is a vendor specific thing from what I've seen.

I see a couple alternatives:

Adopt the card as internal storage, this would encrypt it (I'm pretty sure).

Cryptomator, which handles file level encryption on-the-fly.

Lineage, if the phone supports it - I think that would give you the settings for SD encryption, but I don't recall for sure, and I don't have a phone with an SD and Lineage handy.

(looks like my answer got lost, retrying..)

Thanks a lot for answering!!

Does anyone know how this adopt thing works on an Android 15 on Xperia? We are a bit lost as we cannot find anything in the settings ... :(

I think Google removed that feature.

I have an Xperia 1 VI and I cannot use the SD as internal storage.

so that means we should just never loose our phones i guess ... ... or switch to the dark (customOS) side ..

How about using an encryption software like DroidFS?

yes, thx for that hint indeed! Looks like I have to jump into that cold water indeed. (have to educate myself first on what that all involves exactly....)

I just am also frustrated that these big corps can make such anti consumer decisions and get away with it ......

so far only option i found (but did not yet try) is for a rooted phone:
