Alpha 2 is persistent till launch. How long that is after alpha release is in the air, but insanely optimistic 6 months, realistic 1.5 years, rough 3 years.
Alpha 2 will have a finite capacity for players, so at some point they will decide they have 'enough' and stop selling access.
We have no idea how many have been sold, how they define 'enough' or how many purchasers will not show up. The only way to be totally sure that you have a spot is to buy one while they are still on sale.
They've said in the past that ample notice will be given before removing access from the stores.
However, I can't see them removing A2 access from the store before A2 gets close to ending. Alpha 1 access was on the store while A1 was ongoing and only got removed 3 or 4 days before A1 ended.

They want to know when Alpha-2 keys will be discontinued in the cosmetic packs.
There’s no firm date for Alpha-2 yet … and keys could be discontinued before then.
We may need to wrangle up @Vaknar on this question.
