Hi, Usually, when I get in my mail, I connect on my computer. Then, I get the authentification on my phone. And I can reach my mail. To day, I tried to connect to my mail directly on my phone. I got the authentification on the same phone. I could reach my mail. Since that time, I lost many of my contacts. I've lost some complet contacts, or part of them. For example, I had no more contact of my friend B, and have only the mail of my friend C, all the informations of my friend D are there, etc. Is it possible that Authentificator have a back up of my contacts? Does Authenticator can cancel the acces to a part of my contacts? Thanks for your help. I was wondering because it's the only different thing I have done today. Yesterday night, I had access to everything, as usual.
