Swiss citizen, sending Euro from German bank account to WISE account in Belgium and from there to Thai bank account. Not exactly monthly and usually 2000 Euro.
Registered at WISE in January 2018.
I remember it included passport copy/upload(?) and a proof of my Thai address.
Can't remember whether it included a face photo upload?
Since then never any additional requirements.
Hope it remains quiet.
Usually I go through the mobile app.
Just logged in at the PC and got a "suspicious logon" message.
Unlocking link to my email and got in.
