There has been a lot of chuntering about not being able to lose WhatsApp messages however hard you try. However I am not 100% convinced.
If you start with WhatsApp on a phone, you can then change SIM cards and still see your messages. After that you can change phones and keep the same SIM card and still see your messages.
Through that there are 2 things - phone and SIM card - and as long as you have one the other part can be authenticated.
However I am not sure that there is an independent ID (such as a Gmail account) which can be used to re-establish your identity if, for example, you lose the phone in the sea.
You would, I assume, have to get a new SIM card with the same number to re- establish the chain. [Although what happens if the number is re-issued after your contract lapses?]
Otherwise your phone and SIM card are just strangers with no access rights.
Anyone know otherwise?
I assume that not many on here have made a determined effort to lose WhatsApp messages (assuming you even use this).
