16. The password n Make up your password from number+road OR road+number n e.g. 16overslade OR overslade16 n Best to use lower case throughout 16Purbeck U3A – 28/3/12

17. Memory Aid n Record the locality with the length of the P/W n E.g. as 16overslade is in Bilton and is 11 characters long…. n So memory aid is: 11Bilton 17Purbeck U3A – 28/3/12
