2. Memorable Passwords – an idea! n You need: n 1. Old house number + street/road n 2. Locality of the road n The further back in your memory the better – old lasts longer! 15Purbeck U3A – 28/3/12

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

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

Memory Aid Plus! n Note that the length tells you where the digits are…… n It also gives you an extra memory jog as to the length n You can record this fairly confident that it cannot be decoded…. 18Purbeck U3A – 28/3/12
