Ehi nostr:nprofile1qqs8t4ehcdrjgugzn3zgw6enp53gg2y2gfmekkg69m2d4gwxcpl04acppemhxue69uhkummn9ekx7mp07rhc3q what happens if I login with the same nsec on two different devices?

Will I be able to see the messages I write on one device only on that device? Will I have the same chats list on boh of them or will I see all the "activity" done on one device only on that device? Meaning the profile is the same, but the history separated?
